Ariadne comes from the Greek Ariádnē (Ἀριάδνη), meaning "most holy" — from ari (intensifier) and hagnos (holy, pure). In Greek mythology, Ariadne was the princess of Crete who gave Theseus the ball of thread that allowed him to escape from the Labyrinth after killing the Minotaur.
Ariadne is rising in the U.S. Today it sits in the U.S. top 600 and is climbing.
Ariadne 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 Ariadne reduce to 7, The Seeker. This is a traditional interpretive system, not a factual claim about the name.
