 Modern scholars generally accept 556-468 BC for his life in spite of some awkward consequences—for example it would make him about fifty years older than his nephew Bacchylides and still very active internationally at about 80 years of age.Other ancient sources also have awkward consequences.For example, according to an entry in the Parian Marble, Simonides died in 468/467 BC at the age of ninety yet, in another entry, it lists a victory by his grandfather in a poetry competition in Athens in 489/488 BC — this grandfather must have been over a hundred years old at that time if the birth dates for Simonides are correct.
