Michael Psellos
The main sources of information about Psellos' life are his own works, which contain extensive autobiographical passages. Michael Psellos was probably born in Constantinople. His family hailed from Nicomedia and, according to his own testimony, counted members of the consular and patrician elite among its ancestors. His baptismal name was Constantine; Michael was the monastic name he chose when he entered a monastery later in life. "Psellos" ('the stammerer') probably was a personal by-name referring to a speech defect.
