Venus

To the ancient Romans, Venus (Greek, Aphrodite) was the goddess of love. She was the wife of Vulcan and the mother of Cupid (although Vulcan was not necessarily his father).

English word: From Venus get the name for Venus, the second planet from the sun, which is often the morning or evening star. We also get venereal, relating to sexual intercourse, especially to describe sexually transmitted disease.

Vulcan

To the ancient Romans, Vulcan (Greek, Hephaestus) was the god of fire, especially in its fearful aspects. He was also the god of metal working, the smith of the gods. Ironically, this ugly god was the husband of the beautiful Venus.

English word: More than one word comes to us from Vulcan, including volcano, vulcanism, and vulcanize. In "Star Trek," Mr. Spock is from the planet Vulcan. Also, many corporations use Vulcan in their names.
