Pseudo-Simeon (or Pseudo-Symeon Magistros) is the conventional name given to the anonymous author of a late 10th-century Byzantine Greek chronicle which survives in a single codex, Parisinus Graecus 1712, copied in the 12th or 13th century.
[2] His main sources are Theophanes the Confessor and Symeon Logothete.
[1][2] For later years, he uses parts of Joseph Genesius and the anonymous Chronicle on Leo the Armenian.
[2] He made use of a lost anti-Photian tract that was also used by Niketas David Paphlagon.
[1] George Kedrenos used Pseudo-Simeon as the model for his own chronicle up to the year 812.
