Sybil f
English: from the name (Greek Sibylla or Sybilla, with confusion over the vowels from an early period) of a class of ancient prophetesses inspired by Apollo. According to medieval theology, they were pagans denied the knowledge of Christ but blessed by God with some insight into things to come and accordingly admitted to heaven. It was thus regarded as a respectable name to be borne by Christians. The classical form Sybilla and the French form Sybille are also occasionally used in the English-speaking world.
Variants: Sibyl, SIBILLA.
