Antigone (Ἀντιγόνη) comes from the Greek anti (worthy of) and gone (one's parents, generation) — meaning "worthy of one's parents." Sophocles's tragedy Antigone (c. 441 BCE) features the heroine who defies King Creon to bury her brother — one of the most studied works in Western literature.
Antigone is rare as a given name but rising. The name carries weight in feminist and philosophical literature — Judith Butler, Simone Weil, and many others have written about her.
Antigone reduces to six — the number of defiant moral worth.
