In Egyptian mythology the Matet Boat was the first of two boats traveled in by Ra, the sun god as he traveled the sky daily with the sun on his head. During the period between dawn and noon, Ra occupies the Matet (growing stronger) boat. During the period between noon and dusk Ra travels in the Sektet (growing weaker) boat. Ra travels the underworld during the night where he encounters and battles many foes. Matet and Sektet seem to have many different spellings and Ra himself is often mixed with another or sometimes several deities dependent upon the period and various locations throughout ancient Egypt.
