Galateia (Γαλάτεια) is the Greek word from gala (milk) — "milk-white." A Nereid sea-nymph loved by the Cyclops Polyphemus — she fell in love instead with the shepherd Acis, whom Polyphemus crushed with a boulder in jealousy. Distinct from the Pygmalion-Galatea.
Galateia 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 Galateia reduce to 2, The Peacemaker. This is a traditional interpretive system, not a factual claim about the name.
