There are two works with the name Gesta Hungarorum.
The Gesta Hungarorum (Latin for The Deeds of the Hungarians), a record of early Hungarian history, is preserved in a mid‑12th century manuscript. Most parts of the text are considered by some contemporary authors as simply inventions (by the author or by his predecessors) and contradicting the Frankish, Czech and other chronicles. Gesta Hungarorum's main subject of controversy concerns the mentioning of the existence of the local states of Gelou, Glad and Menumorut in Transylvania at the arrival of the Magyars in the 10th century - see Origin of Romanians.
Hypotheses about the identity of the anonymous author include:
Péter Pósa, bishop of Bosnia
The chancellor of King Béla II of Hungary (1131-1141). If this is true, the author could be a certain Petrus who was in 1124 the chancellor of the previous king Stephen II.
The chancellor of King Béla III of Hungary (1172-1196).
The other Gesta Hunnorum et Hungarorum was written by Simon of Keza.
The GestaHungarorum (Latin for The Deeds of the Hungarians), a record of early Hungarian history written by the otherwise unknown author Magister P, who is often cited simply as Anonymous.
