### Note

Capital M for the planet and the god; small m for the metal. The planet's order: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune. Myth: Mercury is the closest to the Sun, but Venus, not Mercury, is the hottest planet, because of its thick atmosphere.

## In Jewish tradition

In Sefer Yetzirah, Mercury is one of the seven planets, or "stars", along with the Sun, Moon, Venus, Mars, Jupiter and Saturn.

**Interpretation.** The seven planets are matched with the seven double letters and the seven days of the week. Mercury is linked with one of those letters.
