Minerva was the Roman goddess of what?

Minerva was the Roman goddess of wisdom and strategic warfare and the sponsor of arts, trade, and strategy.

Following the Greek myths around Athena, she was born of Metis, who had been swallowed by Jupiter, and burst from her father's head, fully armed and clad in armor. Jupiter forcefully impregnated the titaness Metis, which resulted in her attempting to change shape to escape him. Jupiter then recalled the prophecy that his own child would overthrow him as he had Saturn, and in turn, Saturn had Caelus.

Fearing that their child would be male, and would grow stronger than he was and rule the Heavens in his place, Jupiter swallowed Metis whole after tricking her into turning herself into a fly. The titaness gave birth to Minerva and forged weapons and armor for her child while within Jupiter's body. In some versions of the story, Metis continued to live inside of Jupiter's mind as the source of his wisdom. Others say she was simply a vessel for the birth of Minerva. The constant pounding and ringing left Jupiter with agonizing pain. To relieve the pain, Vulcan used a hammer to split Jupiter's head and, from the cleft, Minerva emerged, whole, adult, and in full battle armor.

Minerva is often depicted with her sacred creature, an owl usually named as the "owl of Minerva", which symbolised her association with wisdom and knowledge as well as, less frequently, the snake and the olive tree.
