Leo the Deacon
Achilles was described by Leo the Deacon (born ca. 950) not as Hellene, but as Scythian, while according to the Byzantine author John Malalas (c. 491–578), his army was made up of a tribe previously known as Myrmidons and "known now as Bulgars". The 12th-century Byzantine poet John Tzetzes also identified the Myrmidons with the Bulgars, whom he also identified with the Paeonians, although the latter may be intended in a purely geographical sense. In the 11th century, Michael Attaleiates called the Rus' Myrmidons, but this usage did not catch on.
