Sia

In Egyptian mythology, Sia is the personification of intellect. He, and Hu, were created from a drop of blood that came from Ra's penis. Sia represents knowledge, while Hu represents the divine utterance and command. They are part of the crew of Ra's sun boat; Sia stands at the prow (except at night, when Upuaut rests there) with Hu right behind him. Sia is shown holding a papyrus.
