Djehuty (Tehuti; G/R Thoth) - "Leader (derivative form)" Ibis-headed Lord of Time, Writing and Wisdom, Djehuty is said to have invented the hieroglyphic script and negotiated five extra days from the moon in order to perfect the 365-day year. As a result of these mythological connections, Djehuty is the patron of writers, teachers, accountants and all persons involved in the dissemination of knowledge, writing and/or calculation. His consorts are alternately Ma'at, Netjeret of Truth and Order; or Seshat, patroness of recordkeeping, libraries and the foundation of buildings. Djehuty is the nominal head of the Ogdoad (group of eight Names of Netjer) honored at the city of Khemenu (Hermopolis of the Greeks), overseeing four pairs of natural syzygies: Eternity (Heh/Hehet), Darkness (Kek/Keket), Water/Potentiality (Nun/Nunet) and Wind/Hiddenness (Amen/Amenet). Along with the ibis, Djehuty is associated with baboons of the genus Cynocephalis, which the ancients observed raising their hands and "singing" to the rising sun; He stands at the side of the scales in the Hall of Two Truths to record the verdict which Yinepu delivers after weighing the deceased's heart against the feather of Ma'at.
