Damo was the daughter of the famous scholar Pythagoras, who lived in the sixth century BCE.
Damo was present during the party that was organized to honor Milo's victories as an athlete. Her father Pythagoras and his disciples Kyros of Zarax and Alcmaeon were also present during the party, as was her younger sister Myia. During this party, she was the one to raise her cup and honor Milo.
She later witnessed how Alcmaeon was torturing a dog in an alleyway and saw how Kyros forcefully stopped him. She then grabbed his arm, forcing Kyros to stop and preventing him from harming Alcmaeon further.
