She was the virgin goddess of music, poetry, medicine, wisdom, commerce, weaving, and the crafts. She 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. Minerva is commonly depicted as tall with an athletic and muscular build, as well as wearing armour and carrying a spear. As the most important Roman goddess, she is highly revered, honored, and respected. Marcus Terentius Varro considered her to be ideas and the plan for the universe personified.
