Background mythology (ibis) -
Thoth was considered one of the more important deities of the Egyptian pantheon, often depicted with the head of an Ibis. (Hence his name means "He who is like the ibis".) His feminine counterpart was Seshat. She was seen as a scribe and record keeper, and her name means she who scrivens (i.e. she who is the scribe), and is credited with inventing writing. She also became identified as the goddess of architecture, astronomy, astrology, building, mathematics, and surveying.
