This is why the Empress' symbol is Venus, goddess of beautiful things and gardens, as wells as sex and love. Venus is the goddess of artists, and helps them painstakingly develop their pieces from clay to statue, from first brushstroke to masterpiece.
Even so, however, the Empress has more in common with Demeter, goddess of abundance, then sensual Venus, as the wheat in the background and the pomegranates on her dress imply. She is the giver of Earthly gifts, the great, fertile mother goddess. Yet at the same time, she can, in anger, withhold as Demeter did when her daughter, Persephone was kidnapped. In fury and grief, she kept the Earth barren till her child was returned to her.
