What evidence suggests that Euripides came from a well-off family?

While some traditions, often cited in the comedies of Aristophanes, suggest that Euripides’ mother was a humble greengrocer, there is better indirect evidence indicating that he came from a well-off family.1

The primary evidence for his affluent background is his intellectual lifestyle and social standing. Euripides possessed a large, personal library and was known to associate with prominent Sophists and philosopher-scientists, such as Anaxagoras. Furthermore, his connections extended to influential political figures, as he was linked to the oligarchs Cleitophon and Theramenes. These associations and his ability to dedicate his life to the pursuit of ideas suggest a level of financial security and social status that would have been difficult to maintain for someone from a working-class background.12
