In the Standard Mesopotamian Calendar, the month starting from the new moon of May is called Simanu (“Month of the Brick Gods”). The King would lay the first brick in the brick mold. Then brickmaking and construction could begin in earnest. The Gods of Bricks and Building were honored in eight rituals that centered on the brick kilns.
For modern people, this can be the time to celebrate masonry and other aspects of building. Think of how bricks provide for safe and snug homes. The beginnings of civilization could be said to be represented by bricks and mortar.
The Gods of Bricks and Building are:
Girra: The God of Fire. The God of Kilns
Kabta: God of Pickaxes, Construction and Bricks
Kulla: The God of Building.
Musdama: The God of Foundations. The God of Architects
Arazu: The God of Completed Construction
Nuska: The God of Fire. The God of Civilization.
Note: In Sumer, the time of the inundations of the fields began at the new moon of May. The month of May-June is known as Sig-ga.
