''Anonymus Bele regis notarius'' ("Anonymous Notary of King Bela") or Master P. ( late 12th century – early 13th century) was the notary and chronicler of a Hungarian King, probably Béla III. Little is known about him, but his latinized name began with ''P,'' as he referred to himself as ''"P. dictus magister".''
Anonymus is famous for his work ''Gesta Hungarorum'' ("The Deeds of the Hungarians"), written in Medieval Latin around 1200. This work provides the most detailed history of the arrival of the Hungarians to the Carpathian Basin (). Most of his attempts to explain the origin of several Hungarian place names are unsupported by modern etymology. Provided by Wikipedia
