Thoth is the Egyptian god of Knowledge. He was widely known as inventor of the written word and credited with the creation of different branches of knowledge.
Considered to be the author of the Book of the Dead, Thoth also acted as scribe to the gods and of the underworld. In this capacity, he stood by during the weighing of the hearts of deceased persons. Hearts lighter or equal to the weight of a feather could move on to a heavenly existence. Thoth’s just decisions in these and other matters made him a respected judge.
Appropriately, one epithet given to Thoth is “The Reckoner of Time and of Seasons.” He possesses the gift of measuring and recording time. Invoked in many spells used in popular magic, Thoth is also seen as a god of magic. Thoth was associated with Hermes, the messenger god, by the Greeks. They were combined to form Hermes Trismegistus.
