Sors \Sors\, n.; pl. Sortes. [L.]

A lot; also, a kind of divination by means of lots.

Sortes Homeric[ae] or Virgilian[ae] [L., Homeric or Virgilian lots], a form of divination anciently practiced, which consisted in taking the first passage on which the eye fell, upon opening a volume of Homer or Virgil, or a passage drawn from an urn which several were deposited, as indicating future events, or the proper course to be pursued. In later times the Bible was used for the same purpose by Christians.
