θηριακή

Forms

θηρῐᾰκή (thēriakḗ) f (genitive θηρῐᾰκῆς); first declension^[1]

Etymology

It is the feminine of the adjective from Ancient Greek θηριακός (thēriakós, “concerning venomous beasts”), used as a noun with ἀντίδοτος (antídotos, “antidote”) understood.^[2][3][1] The adjective is formed from θηρίον (thēríon, “wild animal”), itself a diminutive of θήρ (thḗr, “beast”),^[1][4] which goes back to Proto-Hellenic *kʷʰḗr and Proto-Indo-European *ǵʰwer-.^[1] Here the “beasts” are above all venomous snakes and other poisonous creatures.^[1][2]

Cognate with Latin ferus (“wild”) and Old Church Slavonic звѣрь (zvěrĭ, “wild animal”), from the same root.^[1]

Earliest recorded meaning

The noun first appears in the 1st-century AD physician Andromachus, quoted by Galen, for an antidote against a poisonous bite.^[2]

Semantic evolution

The adjective it comes from had been used of works on venomous animals: Nicander's poem on antidotes was called Θηριακά (Thēriaká), and Dioscorides calls a medicinal wine θηριακός.^[2] Galen speaks of “theriac drugs”, and the substantive θηριακή became the name of the famous compound antidote.^[2]

Byzantine texts use it in veterinary medicine (the Hippiatrica) and in Constantine Porphyrogenitus, with a spelling θεριακή.^[3] The vernacular kept the word for a remedy against poisonous bites, given for instance to a hawk.^[5] A wine poem calls wine, figuratively, “the theriac of the young”.^[5] Kriaras notes that the form and sense still live in Modern Greek dialects.^[5]

Latin borrowed it as theriaca, whence Old French triacle and the English treacle, first a medicinal compound against poison and snakebite.^[4]
