Sappho (Σαπφώ, c. 630-570 BCE) was the Greek lyric poet of the island of Lesbos — Plato called her "the Tenth Muse." Her poems of love and longing survive only in fragments but defined Western lyric poetry.
The words "lesbian" and "sapphic" derive from her name and island.
Sappho does not currently appear in the US Social Security Administration's top 1,000 girls' names, so we don't publish a US rank or birth count for it. That says nothing about the name's standing elsewhere in the world — only that it sits outside the ranked US data we rely on.
In Pythagorean numerology the letters of Sappho reduce to 3, The Communicator. This is a traditional interpretive system, not a factual claim about the name.
