Tyr

Týr, Tíw , and Ziu is a god in. Stemming from the deity *Tīwaz and ultimately from the  deity *, little information about the god survives beyond Old Norse sources. Due to the etymology of the god's name and the shadowy presence of the god in the extant Germanic corpus, some scholars propose that Týr may have once held a more central place among the deities of early Germanic mythology.

Týr is the namesake of the, a letter of the  corresponding to the Latin letter T. By way of the process of , the deity is the namesake of ('Týr's day') in Germanic languages, including English. ', in which Romans interpreted other gods as forms of their own, generally renders the god as ', the ancient Roman war god, and it is through that lens that most Latin references to the god occur. For example, the god may be referenced as Mars Thingsus (Latin 'Mars of the Thing') on 3rd century Latin inscription, reflecting a strong association with the Germanic, a legislative body among the ancient Germanic peoples.

In, from which most surviving narratives about gods among the Germanic peoples stem, Týr sacrifices his arm to the monstrous wolf , who bites off his limb while the gods bind the animal. Týr is foretold to be consumed by the similarly monstrous dog during the events of. In Old Norse sources, Týr is alternately described as the son of the  (in ') or of the god  (in ').  makes reference to an unnamed otherwise unknown consort, perhaps also reflected in the continental Germanic record (see ).

Various place names in Scandinavia refer to the god, and a variety of objects found in England and Scandinavia may depict the god or invoke him.

Name and T-rune
The Old Norse Týr has s including Old English tíw and tíʒ, and Old High German Ziu. A cognate form appears in Gothic to represent the T rune (discussed in more depth below). Like Latin ' and Greek ', Proto-Germanic *Tīwaz ultimately stems from the  *. Outside of its application as a theonym, the Old Norse common noun týr means '(a) god' (plural tívar). In turn, the theonym Týr may be understood to mean "the god". Modern English writers frequently anglicize the god's name by dropping the proper noun's, rendering Old Norse Týr as Tyr.

The modern English weekday name Tuesday means 'Tíw's day', referring to the Old English extension of the deity. Tuesday derives from Old English tisdæi (before 1200), which develops from an earlier tywesdæi (1122), which itself extends from Old English Tīwesdæg (before 1050). The word has cognates in numerous other Germanic languages, including Old Norse týsdagr, Frisian tīesdi, Old High German zīostag, Middle High German zīestac, and zīstac. All of these forms derive from a Proto-Germanic weekday name meaning 'day of Tīwaz', itself a result of  of Latin dies Martis (meaning 'day of '). This attests to an early Germanic identification of *Tīwaz with Mars.

The god is the namesake of the rune representing /t/ (the ) in the, the indigenous alphabets of the ancient Germanic peoples prior to their adaptation of the. The name of the rune first occurs in the historical record as tyz, a character in the (4th century). The name of Týr may occur in runes as on the 8th century.

Germanic weekday names for 'Tuesday' that do not transparently extend from the above lineage may also ultimately refer to the deity, including modern German Dienstag, Middle Dutch dinxendach and dingsdag. These forms may refer to the god's associate with the, a traditional legal assembly common among the ancient Germanic peoples with which the god is associated. This may be either due to another form of the god's name (Proto-Germanic *Þingsaz, meaning 'god of the thing') or may simply be due to the god's strong association with the assembly.

A variety of place names in Scandinavia refer to the god. For example, Tyrseng,, Jutland, Denmark (Old Norse *Týs eng, 'Týr's meadow') was once a stretch of meadow near a stream called Dødeå ('stream of the dead' or 'dead stream'). Viby also contained another theonym, Onsholt ("Odin's "), and religious practices associated with Odin and Týr may have occurred in these places. A dedicated to  that was likely a Christianization of prior indigenous pagan practice also exists in Viby. Viby may mean "the settlement by the sacred site". Archaeologists have found traces of sacrifices going back 2,500 years in Viby.

Roman era
While Týr's etymological heritage reaches back to the Proto-Indo-European period, very few direct references to the god survive prior to the Old Norse period. Like many other non-Roman deities, Týr receives mention in Latin texts by way of the process of , in which Latin texts refer to the god by way of a perceived counterpart in. Latin inscriptions and texts frequently refer to Týr as.

The first example of this occurs on record in Roman senator 's ethnography Germania:
 * translation:
 * Among the gods Mercury is the one they principally worship. They regard it as a religious duty to sacrifice to him, on fixed days, human as well as other sacrificial victims. Hercules and Mars they appease by animal offerings of the permitted kind. Part of the Suebi sacrifice to Isis as well.

These deities are generally understood by scholars to refer to *Wōđanaz (known widely today as Odin), *Þunraz (known today widely as Thor), and *Tīwaz, respectively. The identity of the remains a topics of debate among scholars. Later in Germania, Tacitus also mentions a deity referred to as  venerated by the in a, a. Some scholars propose that this deity is in fact *Tīwaz.

A has been discovered during excavations at  at  in England that had been erected at the behest of Frisian legionaries. The altar dates from the 3rd century CE and bears the Latin inscription Deo Marti Thingso Et Duabus Alaisiagis Bede Et Fimmilene. In this instance, the epithet Thingsus is a Latin rendering of Proto-Germanic theonym *Þingsaz. This deity is generally interpreted by scholars to refer to Týr. The goddesses referred to as Beda and Fimmilene are otherwise unknown, but their names may refer to Old Frisian legal terms.

In the sixth century, the Roman historian writes in his  that the Goths, an east Germanic people, saw the same "Mars" as an ancestral figure:
 * translation:
 * Moreover so highly were the Getae praised that Mars, whom the fables of poets call the god of war, was reputed to have been born among them. Hence Vergil says:
 * "Father Gradivus rules the Getic fields."
 * Now Mars has always been worshipped by the Goths with cruel rites, and captives were slain as his victims. They thought that he who was lord of war ought to be appeased by the shedding of human blood. To him they devoted the first share of the spoil, and in his honor arms stripped from the foe were suspended from trees. And they had more than all races a deep spirit of religion, since the worship of this god seemed to be really bestowed upon their ancestor.

Viking Age and post-Viking Age
By the Viking Age, *Tīwaz had developed among the into Týr. The god receives numerous mentions in North Germanic sources during this period, but far less than other deities, such as, , or. The majority of these mentions occur in the , compiled in the 13th century from traditional source material reaching into the pagan period, and the Prose Edda, composed by Icelandic and politician  in the 13th century.

Poetic Edda
Although Týr receives several mentions in the Poetic Edda, of the three poems in which he is mentioned—', ', and —only the incomplete poem, Hymiskviða, features him in a prominent role. In Hymiskviða, Týr says that his father, Hymir, owns a tremendous cauldron with which he and his fellow gods can brew fathoms of ale. Thor and Týr set out to retrieve it. Týr meets his nine-hundred headed grandmother ("who hates him"), and a girl clad in gold helps the two hide from Hymir.

Upon his return from hunting, Hymir's wife (unnamed) tells Hymir that his son has come to visit, that Týr has brought with him Thor, and that the two are behind a pillar. Hymir immediately smashes the pillar and nine nearby drinking vessels. The vessel containing Týr and Thor, particularly strong in its construction, does not break, and out of it the two gods stride.

Hymir sees Thor and his heart jumps. The jötunn orders three headless oxen boiled for his guests, and Thor eats two of the beasts. Hymir tells the two that the following night, "we'll have to hunt for us three to eat". Thor asks for bait so that he might row out into the bay. Hymir says that the god can take one of his oxen for bait; Thor immediately chooses a black ox, and the poem continues without further mention of Týr.

In Sigrdrífumál, the valkyrie imparts in the hero  knowledge of various. One charm invokes the god Týr:
 * translation:
 * 'You must know victory-runes
 * if you want to know victory. Carve them
 * into your sword's hilt, on the blade guards
 * and the blades, invoking Tyr's name twice.'

In Lokasenna, the gods hold a feast. Loki bursts in and engages in, a contest of insults, with the gods. The prose introduction to the poem mentions that "Tyr was in attendance, even though he had only one hand because the wolf Fenrir had recently ripped off the other while the wolf was being bound." Loki exchanges insults with each of the gods. After Loki insults the god, Týr comes to Freyr's defense. Loki says that "you can't be the right hand of justice among the people" because his right hand was torn off by Fenrir, elsewhere described as Loki's child. Týr says that although he misses his hand, Loki misses Fenrir, who is now bound and will remain so until the events of.

Loki's response contains an otherwise unknown claim about Týr's otherwise unidentified consort: "Shut up, Tyr, my son came from your wife. And you haven't been paid a penny or an ell of cloth as recompense for this, you rat."

Prose Edda
The Prose Edda sections ' and ' reference Týr several times. The god is introduced in part 25 of the Gylfaginning section of the book:
 * translations (notes are Faulkes's own):
 * High said: 'There is also an As called Tyr. He is the bravest and most valiant, and he has great power over victory in battles. It is good for men of action to pray to him. There is a saying that a man is ty-valiant who surpasses other men and does not hesitate. He was so clever that a man who is clever is said to be ty-wise. It is one proof of his bravery that the Æsir were luring Fenriswolf so as to get the fetter Gleipnir on him, he did not trust them that they would let him go until they placed Tyr's hand in the wolf's mouth as a pledge. And when the Æsir refused to let him go then he bit off the hand at the place that is now called the wolf-joint [wrist], and he is one-handed and he is not considered a promoter of settlements between people.

This tale receives further treatment in section 34 of Gylfaginning ("The Æsir brought up the wolf at home, and it was only Tyr who had the courage to approach the wolf and give it food."). Later still in Gylfaginning, High discusses Týr's foreseen death during the events of :
 * Anthony Faulkes translation:
 * Then will also have got free the dog Garm, which is bound in front of Gnipahellir. This is the most evil creature. He will have a battle with Tyr and they will each be the death of each other.

Skáldskaparmál opens with a narrative wherein twelve gods sit upon thrones at a banquet, including Týr. Later inSkáldskaparmál, the skald god tells  (described earlier in Skáldskaparmál as a man from the island of ) how s function. By way of kennings, Bragi explains, one might refer to the god Odin as "Victory-Tyr", "Hanged-Tyr", or "Cargo-Tyr"; and Thor may be referred to as "Chariot-Tyr".

Section nine of Skáldskaparmál provides skalds with a variety of ways in which to refer to Týr, including "the one handed As", "feeder of the wolf", "battle-god", and "son of Odin". The narrative found in Lokasenna occurs in prose later in Skáldskaparmál. Like in Lokasenna, Týr appears here among around a dozen other deities. Similarly, Týr appears among a list of Æsir in section 75.

In addition to the above mentions, Týr's name occurs as a kenning element throughout Skáldskaparmál in reference to the god Odin.

Archaeological record
Scholars propose that a variety of objects from the archaeological record depict Týr. For example, a gold  from, Sweden, features a person receiving a bite on the hand from a beast, which may depict Týr and Fenrir. A Viking Age in, ,  may depict Týr and Fenrir.

Scholarly reception
Due in part to the etymology of the god's name, scholars propose that Týr once held a far more significant role in Germanic mythology than the scant references to the deity indicate in the Old Norse record. Some scholars propose that the prominent god Odin may have risen to prominence over Týr in prehistory, at times absorbing elements of the deity's domains. For example, according to scholar Hermann Reichert, due to the etymology of the god's name and its transparent meaning of "the god", "Odin ... must have dislodged Týr from his pre-eminent position. The fact that Tacitus names two divinities to whom the enemy's army was consecrated ... may signify their co-existence around 1 A.D."

The Sigrdrífumál passage above has resulted in some discourse among. For example, regarding the passage, runologists Mindy MacLeod and Bernard Mees say:
 * Similar descriptions of runes written on swords for magical purposes are known from other Old Norse and Old English literary sources, though not in what seem to be religious contexts. In fact very few swords from the middle ages are engraved with runes, and those that are tend to carry rather prosaic maker's formulas rather than identifiable 'runes of victory'. The call to invoke Tyr here is often thought to have something to do with t-runes, rather than Tyr himself, given that this rune shares his name. In view of Tyr's martial role in Norse myth, however, this line seems simply to be a straightforward religious invocation with 'twice' alliterating with 'Tyr'.
