Little is known for certain about Sappho's life. What is known comes from three sources: Sappho's surviving poetry, other ancient writings about her, and evidence about archaic Greece in general. She was born on the Greek island of Lesbos around 630 BC, in either Eresos or Mytilene. Her parents' names are not known for certain, though her mother is often called Kleïs. Ancient tradition gave at least eight possible names for her father. One ancient story, which might be based on a now-lost poem by Sappho, says that her father died when Sappho was still a child. Sappho was said to have three brothers, called Charaxos, Larichos, and Eurygios. The "Brothers poem", discovered in 2014, talks about Charaxos and Larichos.
