In English we know him by his Greek name, Thoth, but this ancient Egyptian god was known as Djehuty or Dhwty. Thoth was the patron of scribes and was considered the inventor of writing. He was usually portrayed as a man with an ibis head, or as a baboon. He was also the god of mathematics, of all the sciences, and every branch of human and divine knowledge. His symbols are the crescent moon, the writing case, the papyrus and the pen.
