The name by which the Picts called themselves is unknown. The Greek word Πικτοί (Latin Picti) first appears in a panegyric written by Eumenius in AD 297 and is taken to mean "painted or tattooed people" (Latin pingere "paint"). This may, however, be due to early folk etymology and the term likely has a Celtic origin, perhaps Pehta, Peihta (meaning "fighters").[1] The Gaels of Ireland and Dál Riata called the Picts Cruithne, (Old Irish cru(i)then-túath), presumably from Proto-Celtic *kwriteno-toutā. There were also people referred to as Cruithne in Ulster, in particular the kings of Dál nAraidi.[2] The Britons (later the Welsh and Cornish) in the south knew them, in the P-Celtic form of "Cruithne", as Prydyn; the terms "Britain" and "Briton" come from the same root.[3] Their Old English name gave the modern Scots form Pechts.[4]
