Sothis

Cyclopedia of Biblical, Theological and Ecclesiastical Literature

the name given by the Egyptians to the dog star, or Sirius. Their year began with the rising of this star, and the coincidence of the latter phenomenon with the new moon marked the great sidereal or world year of 1461 civil years. So this was also, in Egyptian mythology, a designation of Isis, and the star Sirius was accordingly sacred to that divinity.
