Perthro Rune Meaning: Symbolism, Upright, Reversed and Divination Use

Perthro is the fourteenth rune of the Elder Futhark, the lot-cup rune of chance, hidden knowledge, and fate about to surface. This guide covers the Perthro rune symbol and its /p/ sound, its place in Heimdall's aett, the Old English peorth stanza, and how Perthro reads upright, reversed, and in bind runes.

What does the Perthro rune mean?

Perthro is the Elder Futhark rune of the lot-cup, and its meaning covers chance, concealed knowledge, and the instant a hidden thing is shaken out where everyone can see it. The name is reconstructed as Proto-Germanic *perþo and appears in Old English as peorth. Although the literal object behind the name is disputed, the divinatory tradition has settled on the image of a vessel that lots are cast from. Perthro rune meaning runs in two directions at once: the cup that keeps its contents private, and the throw that makes them public. Readers turn to Perthro for questions about what is not yet known, what is still forming, and what is being decided outside the querent's hands. The rune carries wyrd, the Norse sense of a pattern already laid down and now unrolling, rather than luck as a modern gambler understands it. Nothing in Perthro is random in the sloppy sense. The contents of the cup were placed there before the throw. When Perthro appears in a spread, the tradition reads it as confirmation that the answer already exists and is simply not visible yet.

Modern rune writers have pushed Perthro meaning in slightly different directions while keeping the same core. Ralph Blum, in The Book of Runes in 1982, glossed it as initiation and a secret matter, and that phrasing has spread through decades of beginner decks and booklets. Edred Thorsson, in Futhark: A Handbook of Rune Magic in 1984, treats Perthro as the lot-cup and the evolutionary force that shakes the pattern loose. Freya Aswynn ties Perthro to Frigg and to the Norns at the well beneath Yggdrasil. Those readings converge because the rune sits at the point where the fixed and the unfolding meet. Lokasenna preserves a line saying that Frigg knows all fate though she herself does not speak it, and that is the exact temperature of a Perthro draw: the knowledge is complete somewhere, just not on your side of the table. Practitioners sometimes call Perthro the rune of the reading itself, the stave that describes what happens when the pieces leave the bag.

Is the Perthro rune about fate or about chance?

Perthro is about fate arriving through the mechanism of chance. In Norse terms the outcome is wyrd, already woven, and the cast of the lot is only the door it comes through. Perthro never promises that the querent can influence the result, but it insists the result is meaningful rather than arbitrary.

What is the Perthro rune in one keyword?

The single keyword most readers give Perthro is mystery, with secret, lot, and chance following close behind. In a one-word rune journal, writing mystery next to Perthro captures the essential posture: information exists, the querent does not have it yet, and the reading is about what happens when it lands.

Why is Perthro called the lot-cup rune?

Perthro is called the lot-cup rune because its shape resembles a vessel on its side and its most persuasive name etymology points to a dice-box or gaming container. Tacitus, in chapter ten of Germania, describes Germanic lot-casting with marked strips of wood scattered on a white cloth, and readers have long linked Perthro to that practice.

What does the Perthro rune symbol look like and what sound does it make?

The Perthro rune symbol is ᛈ: a straight vertical stave on the left with two arms reaching to the right, one from the top and one from the bottom, each angled inward so the whole figure reads as an open cup or lidless box lying on its side. The mouth faces right when Perthro is upright. Perthro is the Elder Futhark letter for the sound /p/ and is transliterated as p in standard scholarly convention, printed in bold p in most rune corpora. Some carvers draw the arms as straight diagonals meeting the stave at sharp angles, others bend them into a squarer bracket, and both forms appear across the surviving material without changing the letter. The Perthro rune symbol is often described as two Kenaz shapes stacked and joined, one opening up and one opening down, which is a useful memory hook when learning to carve it. Because the figure has no horizontal strokes, it cuts cleanly into wood along the grain in the same way the rest of the futhark does, every stroke crossing the fibers rather than splitting them.

Perthro is genuinely rare in surviving Elder Futhark inscriptions, and the reason is linguistic rather than magical. The /p/ sound was uncommon in early Germanic because Proto-Indo-European p had shifted to f under Grimm's law, so the letter mostly had loanwords and a few odd native forms to carry. A rune that spells a sound nobody needs does not get carved often. Perthro survives clearly on the futhark row inscriptions rather than in running text, and the Kylver Stone from Gotland, dated to roughly 400 CE, shows it in sequence with the other twenty-three. When the Younger Futhark reduced the row to sixteen staves in the eighth century, Perthro was one of the casualties, and Scandinavian writers spelled p with the b rune instead. The Anglo-Saxon Futhorc kept it, which is why the only rune poem stanza for this stave is in Old English. For modern rune workers the practical consequence is that Perthro has thinner historical documentation than Fehu or Thurisaz, and most of what is said about its divinatory sense comes from the twentieth century forward, built out from the shape and the one surviving stanza.

Which direction does the Perthro rune symbol open?

The Perthro rune symbol opens to the right when upright, with the vertical stave forming the closed back of the cup. Turning the stave one hundred and eighty degrees swings the mouth to the left, which is what produces the reversed or merkstave form. Mirroring it left to right is a carving variant, not a reversal.

How should Perthro be carved on wood or bone?

Perthro is carved by cutting the vertical stave first, then the upper arm from the top of the stave outward and downward, then the lower arm from the bottom outward and upward. Keeping both arms the same length gives the balanced cup shape. Carvers usually redden the cuts afterward so the open mouth stays legible at a glance.

Why does Perthro rarely appear in Viking Age inscriptions?

Perthro rarely appears in Viking Age inscriptions because the Younger Futhark dropped it entirely around the eighth century, leaving Scandinavian writers to render p with the b rune. Even in the older Elder Futhark period the /p/ sound was scarce in Germanic vocabulary, so Perthro shows up mainly in complete futhark rows rather than in ordinary words.

Where does the Perthro rune sit in the Elder Futhark and which aett is it in?

Perthro is the fourteenth rune of the Elder Futhark and the sixth rune of the second aett, the group commonly named for Hagal or attributed to Heimdall. The second aett runs Hagalaz, Nauthiz, Isa, Jera, Eihwaz, Perthro, Algiz, Sowilo, and Perthro sits between Eihwaz and Algiz in that sequence. Readers who work with aett structure treat this middle group as the row of trial and process, opening with the hailstorm of Hagalaz and closing with the sun of Sowilo, and Perthro falls in the stretch where the pressure has already done its work and something is being brought through. Its neighbors sharpen the sense. Eihwaz is the yew, the vertical axis that runs between worlds and stands for the passage through death. Algiz is the elk-sedge, the raised hand of protection. Perthro sits between the descent and the shield, which is precisely where a practitioner would expect to find a rune of concealed knowledge and emergence. The number fourteen is used by rune workers who assign numeric values, and Perthro is sometimes counted as the sixth stave of its own row for the same purpose.

The position matters in practice because many rune readers use aett membership as a first-pass filter on what a draw is talking about. A spread heavy in the second aett is read as pressure, constraint, and process, against the material and social tone of the first aett. Perthro drawn alongside first-aett staves such as Fehu or Gebo pulls the mystery down into concrete affairs, often money or an agreement whose terms are not fully disclosed. The Kylver Stone preserves Perthro in its expected slot, the main evidence that the ordering is old rather than a modern reconstruction. The Vadstena bracteate from Sweden also lays out the row in aettir with dividers, giving the eight-eight-eight grouping historical footing. That structure is what lets a reader say Perthro belongs to Heimdall's row and mean something concrete by it.

Which rune comes before and after Perthro?

Eihwaz, the yew rune, comes immediately before Perthro in the Elder Futhark, and Algiz, the elk-sedge rune of protection, comes immediately after. Perthro at position fourteen therefore sits between the world-axis stave and the shielding stave, a placement readers use to argue that Perthro governs what is brought up from below and then guarded.

What number is the Perthro rune?

Perthro is number fourteen in the standard Elder Futhark ordering of twenty-four staves, and number six within the second aett. Rune workers who use numerology assign it fourteen when reading the row straight through, and six when working aett by aett. Both counts appear in modern practice and neither is historically documented in the inscriptions.

Why does Perthro's place in Heimdall's aett matter in a reading?

Perthro's place in the second aett tells a reader that the question involves process rather than possession. The second aett opens with Hagalaz and closes with Sowilo, tracing disruption through to breakthrough, and Perthro falls after the hard staves of Nauthiz, Isa, and Eihwaz. That placement frames Perthro as a result forming under pressure, not a windfall.

What do the rune poems say about the Perthro rune?

Only one rune poem describes Perthro: the Old English Rune Poem, where the stave appears as peorth. The Norwegian and Icelandic rune poems describe the Younger Futhark, a sixteen-rune row that has no p rune at all, so neither poem contains a Perthro stanza and any source claiming otherwise is inventing one. The Old English stanza reads: Peorth byth symble plega and hlehter wlancum, thar wigan sittath on beorsele blithe aetsomne. It translates roughly as: Peorth is always play and laughter among proud men, where warriors sit in the beer hall, cheerful together. The manuscript that carried the Old English Rune Poem, Cotton Otho B.x, was destroyed in the Ashburnham House fire of 1731, and the text survives because George Hickes had printed it in his Thesaurus of the northern languages a generation earlier. A word or two in the middle of the peorth stanza is an editorial restoration rather than a certain reading, which is one more reason the rune resists confident translation.

What the stanza gives a reader is atmosphere rather than definition. Peorth belongs to the mead-bench, to gaming and noise, to men amusing themselves in company. It says nothing explicitly about dice, cups, or fate, and the gambling reading is inferred from the word plega, which covers play, sport, and games, together with the setting. That inference is old and reasonable, since dice and gaming pieces are common finds in Germanic and Scandinavian graves, and the beer hall is exactly where lots would be thrown for stakes. Compare the neighboring stanzas: the yew is described by its bark and roots, hail by its turning to water, while peorth names no object at all. Some scholars read that evasiveness as the poet not knowing what the rune name meant either, since the poem was composed centuries after the Elder Futhark was in daily use. Modern divinatory practice has taken the gaming hall and pulled the lot-cup out of it, and that is the honest chain of reasoning behind the standard Perthro rune meaning.

What is the Old English Rune Poem stanza for peorth?

The peorth stanza reads: Peorth byth symble plega and hlehter wlancum, thar wigan sittath on beorsele blithe aetsomne. In modern English: Peorth is always play and laughter among proud men, where warriors sit in the beer hall, cheerful together. It is the only surviving rune poem stanza for this stave, and it names no object.

Why is there no Icelandic or Norwegian rune poem for Perthro?

There is no Icelandic or Norwegian stanza for Perthro because both poems describe the Younger Futhark, which reduced the row to sixteen staves and eliminated the p rune outright. Scandinavian scribes wrote p with the b rune instead. Any modern source quoting an Icelandic Perthro verse has borrowed it from somewhere else or fabricated it.

Does the Old English stanza actually mention dice?

The Old English stanza does not mention dice, cups, or lots. It mentions plega, meaning play or sport, and hlehter, meaning laughter, in a beer hall setting. The gambling association is an inference drawn from that vocabulary plus the name's likely link to a gaming container, not a direct statement in the poem itself.

Why is the meaning of the name Perthro disputed?

The name Perthro is disputed because no Germanic word matches it cleanly, leaving several competing reconstructions with no decisive evidence. The gaming-container theory derives peorth from a word for a dice-box or lot-cup, possibly borrowed from a neighboring language, and it fits the beer-hall stanza better than any rival. A second proposal reads peorth as a pear tree or pear-wood, connecting it to Latin pirum, and points out that the Old English rune poem names trees for several other staves. A third links the name to a Slavic or Celtic root and treats it as a loanword that entered Germanic along a trade route. A fourth, popular in modern occult writing, ties Perthro to a word for the womb or birth passage and reads the rune as gestation and delivery. A fifth reads it as a hearth or fireplace. The Gothic alphabet list in Codex Vindobonensis 795, associated with Alcuin's circle, gives the letter name as pairthra, confirming the name is old without settling what it meant.

For a practicing reader the dispute is less of a problem than it looks, because the candidate meanings all fold into the same divinatory field. A dice-cup, a womb, and a hearth are all containers whose contents are hidden until they come out, and the tradition reads Perthro as exactly that. The pear tree is the outlier, though it has serious linguistic backing rather than being a fringe idea. Where the dispute does matter is in how much authority a modern gloss can claim. When a booklet states flatly that Perthro means the womb of the Great Mother, that is twentieth-century interpretation presented as etymology, and knowing the difference keeps a reader honest with clients. The safest formulation in a reading is functional rather than lexical: Perthro is the container from which the unknown emerges. That holds whichever reconstruction eventually wins, and it is the shared thread every serious commentator on the rune has worked from.

Does Perthro mean vulva or womb?

The womb reading of Perthro is a modern interpretive tradition rather than a settled etymology. It has been argued from a proposed Slavic cognate and from the cup shape of the stave, and it is widespread in contemporary occult writing, but it is not the consensus derivation. Readers use it productively for fertility and birth questions without treating it as proven.

Is Perthro a pear tree?

The pear tree derivation of Perthro is a genuine scholarly proposal, linking Old English peorth to Latin pirum and to the tree names that appear in other stanzas of the same rune poem. It has never displaced the gaming-container theory, partly because the peorth stanza describes a hall scene rather than a tree, which is the pattern the poem uses for other tree runes.

What is the Gothic name related to Perthro?

The Gothic letter corresponding to Perthro is named pairthra in the alphabet list preserved in Codex Vindobonensis 795, a manuscript connected with Alcuin's circle. The form confirms that a Germanic letter name beginning with p and containing a th sound was already in circulation, but it supplies no gloss, so the meaning stays open.

What does the Perthro rune mean upright in a reading?

Perthro upright means the cup is held open and something concealed is about to be revealed. Readers take it as a signal that hidden information is in play and moving toward disclosure, whether that is a secret someone is holding, a development still forming out of sight, or an opportunity that will arrive through a channel the querent has not been watching. Upright Perthro favors divination, dreamwork, and any question about what is happening beneath the visible surface. It carries a strong flavor of initiation, of being admitted to something previously closed, which is why it turns up so often in readings about spiritual training, apprenticeships, and formal admissions. Perthro upright also reads as a favorable throw where luck is genuinely involved, though the tradition frames that as wyrd cooperating rather than as odds tilting. In timing questions Perthro upright says soon but not scheduled, since the contents are already in the cup and only the moment of the throw is outstanding. The rune rewards patience and observation and punishes forcing, because the cup gives up its contents on its own terms.

In practical spreads the upright Perthro rune shifts meaning with the domain of the question. On career and money, it points to an offer or a piece of information not yet disclosed, often something arriving through a contact rather than a formal channel, and it favors applications where selection feels partly out of the applicant's control. On health and family, Perthro upright commonly reads as pregnancy or as a diagnosis that has not yet been named, and experienced readers deliver that carefully rather than as an announcement. On spiritual questions it is the strongest single indicator in the futhark that a threshold is being crossed and that the querent should say yes to the training, the group, or the practice being offered. Across all of these the instruction is the same: gather, and do not demand the answer before it is ready to arrive.

What does the Perthro rune mean in a love reading?

Perthro upright in a love reading points to unspoken feeling and information still held back, usually in the querent's favor. It often shows a person whose interest is real but undeclared, or a relationship with a dimension neither party has named. Perthro rarely describes a public, settled bond, since its subject is what has not surfaced yet.

What does Perthro mean for career and money questions?

Perthro upright in a career reading indicates an opportunity moving toward the querent through a channel they cannot see, often an unadvertised role, a referral, or a decision being made about them elsewhere. On money it can flag an unexpected sum or a financial detail not yet disclosed, and it favors patience over aggressive pursuit.

Is Perthro a yes or a no?

Perthro is neither a clean yes nor a clean no, and readers who force binary answers usually score it as not yet. Upright Perthro says the outcome exists and is favorable to disclosure, so many readers treat it as a qualified yes with a delay attached. Perthro reversed in a yes-no draw reads as no, or as ask again later.

What does Perthro reversed mean?

Perthro reversed means the cup has turned its mouth away, and the secret it holds is staying shut. Because the stave is asymmetrical, Perthro has a genuine merkstave form: rotate it and the opening that faced right now faces left. Readers interpret Perthro reversed as concealment that has become a problem, information deliberately withheld, a revelation that fails to arrive, or a person trading on what they know rather than sharing it. It commonly signals stagnation in a situation whose progress depends on disclosure, and it warns against expecting luck to solve something that requires direct action. In its harsher readings, Perthro reversed covers gambling that has stopped being play, an unhealthy attachment to the past, and secrets kept so long they have calcified into a barrier. Around health and family questions it can indicate a delay in a birth or a process that will not complete on its own timetable. Perthro reversed also flags divination going nowhere, and many readers treat it as an instruction to close the session and return to the question later rather than to keep casting.

The reversed-rune question is contested, and it lands on Perthro more sharply than on most staves. Nine of the twenty-four Elder Futhark runes look identical rotated, so any reading system that uses reversals is applying it unevenly across the row, and some practitioners drop reversals entirely and take context from surrounding staves instead. Perthro sits with the reversible group, which means readers who use merkstave positions will encounter Perthro reversed frequently, and it is worth deciding your policy before you cast rather than mid-reading. Practitioners who avoid reversals recover the same content from the neighbors: Perthro next to Isa or Nauthiz gives the blocked-secret picture anyway. Practitioners who do use reversals tend to give Perthro reversed a lighter touch than its reputation suggests, treating it as a locked door rather than a disaster. In either system the practical counsel is consistent: stop waiting for a revelation, act on what is already visible, and pursue disclosure directly instead of hoping the cup will tip on its own.

Is Perthro reversed a bad omen?

Perthro reversed is an obstructive rune rather than a catastrophic one. It describes information that stays hidden, a process that stalls, or luck that does not arrive, none of which are ruin. Most readers deliver Perthro reversed as a redirection: stop waiting on a disclosure that is not coming and work with the facts already in hand.

What does Perthro reversed say about a secret?

Perthro reversed says the secret is holding and will not surface on its own within the timeframe of the question. It can mean someone is actively withholding, or simply that the matter is not ready. Readers pair it with the surrounding staves to judge which, since a nearby Ansuz suggests a conversation is what breaks the silence.

Should you read Perthro reversed at all?

Whether to read Perthro reversed depends on your system, and both approaches are defensible. Perthro is asymmetrical, so a reversal is physically visible, but nine runes in the futhark cannot reverse at all, which makes any reversal system partial. Readers who skip merkstave positions get similar information from Perthro's neighbors in the spread.

How is the Perthro rune used in bind runes and rune magic?

The Perthro rune is used in magic for divination, concealment, and bringing hidden things to term, and it binds readily because its vertical stave shares a spine with most of the futhark. A Perthro bind rune is built by carving the stave once and hanging the arms of Perthro and the arms of a partner rune off the same line. Perthro joined with Ansuz is the standard working for clear reception in divination, pairing the container with the mouth that speaks. Perthro with Jera is used for timing, asking that what is in the cup ripen and fall at the right point in the cycle. Perthro with Berkano is carved for pregnancy and safe delivery, since Berkano supplies the birch and the nurturing that Perthro's container implies. Perthro with Algiz is worn for protection during trance work, keeping the practitioner shielded while the cup is open. Rune workers also carve Perthro alone on divination pouches and lot-box lids, marking the tool as belonging to the work of drawing out the unknown.

Beyond bind runes, Perthro appears in three recurring practices. The first is galdr, the chanted vocalization of the rune name, where practitioners hold the vowel and let the final consonants hiss, often repeating the name nine times over a set before a reading. The second is staining and consecration, where Perthro is the stave marked on the container that holds the set rather than on any individual piece, so the cup itself carries the rune of the cup. The third is the doubled Perthro, two staves set mouth to mouth so the arms close into a diamond or a sealed box. Practitioners read that figure as a secret held rather than a secret released, and it is carved for confidentiality: on the cover of a journal, on a lockbox, on a piece of jewelry worn while carrying something you cannot discuss. Tacitus records in Germania that lots were cut from a nut-bearing branch, marked, scattered on white cloth, and lifted three at a time, and practitioners reconstructing that rite often carve Perthro on the cloth's hem.

Which runes bind best with Perthro?

Ansuz, Jera, Berkano, and Algiz are the four staves most often bound with Perthro. Ansuz opens communication of what the cup holds, Jera sets timing, Berkano governs birth and nurture, and Algiz shields the practitioner while the working is open. All four share Perthro's vertical stave, which makes the bind rune clean to carve.

What does a doubled Perthro bind rune mean?

A doubled Perthro bind rune sets two Perthro staves mouth to mouth so the arms close into a sealed box or diamond. Practitioners carve it for confidentiality rather than revelation, marking journals, containers, and jewelry worn while holding information that must not be spoken. It inverts the usual Perthro working, sealing the cup instead of tipping it.

How is Perthro used in galdr?

In galdr the rune name is chanted aloud over a set or a carved object, with practitioners sustaining the vowels and drawing out the final breath of the name. Perthro is commonly intoned nine times before a divination session, either over the whole bag of staves or over the cup they are cast from, to mark the beginning of the work.

How do you interpret the Perthro rune with other runes in a spread?

Perthro takes its specific meaning from its neighbors more than most staves do, because the rune names a container without naming its contents. Perthro with Berkano reads as pregnancy, a new venture in its first weeks, or something nurtured out of sight. Perthro with Fehu points to money whose source or amount has not been disclosed, often an inheritance or a payment in process. Perthro with Ansuz says the secret comes out through speech, a conversation, or a message, and it is the friendliest pairing for anyone waiting on news. Perthro with Isa or Nauthiz means the cup is frozen shut and nothing is coming, which is the same picture a reversed Perthro gives without needing the reversal. Perthro with Hagalaz warns that what emerges will be disruptive rather than welcome. Perthro with Jera sets a natural timetable and counsels waiting for the season to turn. Perthro with Eihwaz, its neighbor in the row, deepens the reading into initiation, deep memory, and matters connected to the dead.

Position matters as much as pairing. Perthro in an outcome position tells the querent the result is not yet visible and the reading has gone as far as it can, which is a legitimate answer rather than a failure of the cast. Perthro in a past position points to an origin the querent does not fully know: family history, or a formative event never seen clearly. Perthro in an obstacle position names missing information as the actual blocker, and the counsel is to go get it rather than to work harder on the visible parts. In a three-rune Norn layout, Perthro in the Skuld position is the classic reading of a future still forming, and most readers will decline to force specifics from it. Drawing Perthro twice in a session, which happens when a set is recast, is traditionally read as the runes commenting on the process itself and asking the reader to change the question. The single most useful discipline with Perthro is to name the container out loud and then let the surrounding staves say what is inside it.

What does Perthro with Berkano mean?

Perthro with Berkano is the standard pregnancy and new-growth pairing in rune reading, combining the hidden container with the birch of birth and nurture. Outside literal pregnancy it reads as a venture in its earliest stage, protected and not yet announced. Readers deliver it as something forming well that should not be exposed too soon.

What does Perthro in the outcome position mean?

Perthro in an outcome position means the result has not surfaced and the spread cannot show it yet. Readers treat this as a real answer rather than a failed cast: the matter is still in the cup. The usual response is to name what is known, decline to guess the rest, and recast after the situation has moved.

How does Perthro read next to Eihwaz?

Perthro next to Eihwaz intensifies into initiation, ancestry, and matters touching the dead, since Eihwaz is the yew that runs between worlds and the two staves are neighbors in the second aett. The pairing often appears in readings about inherited patterns, grief that has not been processed, or a spiritual passage the querent is already inside.

Frequently Asked Questions

What does the Perthro rune mean in one sentence?

Perthro means the lot-cup: hidden knowledge, chance, and the moment a concealed thing is shaken out into the open. Perthro rune meaning covers everything that already exists but has not yet been seen, which is why readers attach it to secrets, gestation, initiation, and outcomes decided by wyrd rather than by the querent's effort.

Is Perthro a good rune to draw?

Perthro is a favorable rune to draw when the question is about something unknown, because it says the answer exists and is close to surfacing. Perthro is frustrating when the question demands a firm date or a fixed commitment, since the rune describes a process still inside the cup rather than a settled result on the table.

What is the Perthro rune symbol?

The Perthro rune symbol is written ᛈ, a vertical stave with two arms projecting to the right from the top and bottom and angling inward, so the figure reads as an open cup or lidless box lying on its side. Perthro is the Elder Futhark letter for the sound /p/ and is transliterated as p.

What does Perthro reversed mean in a love reading?

Perthro reversed in a love reading points to something withheld: a person who will not say what they want, a history one partner has not disclosed, or a connection stuck waiting for information that never arrives. Perthro reversed rarely accuses anyone of lying; it describes a silence that has hardened into an obstacle.

Which god or goddess is associated with the Perthro rune?

Perthro is most often associated with Frigg and with the Norns, Urd, Verdandi, and Skuld, who tend the well at the root of Yggdrasil. Lokasenna says Frigg knows all fate though she herself does not speak it, which is exactly the posture Perthro takes in a reading: knowledge held, not yet given.

Is Perthro the same as the blank rune?

Perthro is not the blank rune. The blank rune was introduced by Ralph Blum in The Book of Runes in 1982 and has no basis in historical inscriptions, while Perthro is one of the twenty-four Elder Futhark staves recorded on the Kylver Stone. Both are read as the unknown, which is why beginners confuse them.

How is the Perthro rune pronounced?

Perthro is usually pronounced PERTH-roh, with the th of thin rather than the th of this, reflecting the reconstructed Proto-Germanic name *perþo. The Old English form peorth is pronounced closer to PEH-orth. Rune workers chanting galdr typically hold the vowels and let the final th hiss out on the breath.
