a prophetess in ancient Greece and Rome
from Greek Sibylla, name of ancient prophetesses
Sybil could see the future - she was like an ancient crystal ball!
Sybil (sibyl) derives from ancient Greek female oracles; the name became synonymous with prophecy but also with hysteria and unreliability, especially after the 1970s 'multiple personality' pop psychology fixation, which weaponized female mental complexity.
Use as a proper noun only. If referencing oracle/prophecy generally, use 'oracle' or 'prophet' (gender-neutral).
["oracle","prophet","seer"]
Ancient sibyls were respected repositories of divine knowledge; modern usage often trivializes them or conflates them with mental illness.
