Sibyl, name given to a woman, or rather to a number of women, much fabled of in antiquity, regarded by Ruskin as representing the voice of God in nature, and, as such, endowed with visionary prophetic power, or what in the Highlands of Scotland is called "second-sight"; the most famous of the class being the Sibyl of Cumæ, who offered King Tarquin of Rome nine books for sale, which he refused on account of the exorbitant sum asked for them, and again refused after she had burnt three of them, and in the end paid what was originally asked for the three remaining, which he found to contain oracular utterances bearing on the worship of the gods and the policy of Rome. These, after being entrusted to keepers, were afterwards burned, and the contents replaced by a commission appointed to collect them in the countries around, to share the same fate as the original collection. The name is applied in mediæval times to figures representative of the prophets who foretold the coming of Christ; the prophets so represented were reckoned sometimes 10, sometimes 12 in number; they are, says Fairholt, "of tall stature, full of vigour and moral energy; the costume rich but conventional, ornamented with pearls and precious stones."
