Damo (Δαμώ) is the Greek mythological short form. **Damo (6th c. BCE)** was the daughter of **Pythagoras and Theano** — entrusted with his secret writings, **she refused to sell them despite living in poverty** in obedience to her father's wishes. A model of Pythagorean fidelity.
Featured in Diogenes Laërtius's Lives of Eminent Philosophers.
Damo reduces to five — the number of Pythagorean fidelity.
