Michael Attaleiates

Michael Attaleiates or Attaliates (Ancient Greek: Μιχαὴλ Ἀτταλειάτης, romanized: Mikhaḕl Attaleiátēs, Byzantine Greek: [mixaˈil atːaliˈatis]; c. 1022 – 1080) was a Byzantine chronicler, public servant and historian active in Constantinople and around the empire's provinces in the second half of the eleventh century. He was a younger contemporary (possibly even a student) of Michael Psellos and likely an older colleague of John Skylitzes, the two other Byzantine historians of the eleventh century whose work survives.
