Phrygian is an Indo-European language, unaffiliated to any branch of the language family. It was spoken from 8th century BC in parts of Asia Minor. Its corpus can be divided chronologically to two parts, the older (Paleo-Phrygian) and later (Neo-Phrygian). Paleo-Phrygian is attested by about 340 very short inscriptions, mainly on seals and vessels, dating from the 8th to the 6th century BC. Neo-Phrygian is attested by 113 funerary documents, consisting of an epitaph and an imprecation, dating from the 1st to the 5th century AD. There is no example of adjective valence.
