Leo the Deacon
In addition to the Bitola inscription where the victory of Samuil, commander of the Bulgarian army, is mentioned in summary form, several medieval historians have written accounts for the battle. Among them were "Leo the Deacon" who was an eyewitness and a direct participant in the campaign; "John Skylitzes" and two other historians "George Kedrin" and "Joannes Zonaras" who repeat the work of Skylitzes. Not only Byzantine historians wrote accounts for the battle, it was also recorded by the Melkite chronicler "Yahaya of Antioch" and the Armenians, "Stephen of Taron" (also known as "Asolic") and "Matthew of Edessa". More details can be found in the commended sermon of Saint Photius of Thessaly.
