Aglaia (Ἀγλαΐα) is one of the three Charites (Graces) in Greek mythology — the goddess of splendor, brightness, and adornment. Her sisters are Euphrosyne (mirth) and Thalia (festivity).
Aglaia is rare as a given name but distinctive.
Aglaia 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 Aglaia reduce to 4, The Builder. This is a traditional interpretive system, not a factual claim about the name.
