In alchemical tradition, seven metals were associated with the seven classical planets, which included the Sun and the Moon (but not Earth). The Sun’s metal was gold. In Hellenistic astrology, each classical planet had its own day of the week. Sól or Sunna was the name of the Sun goddess in Germanic mythology. English and other Germanic languages keep the association of Sun and Sunday. Other solar deities include goddesses Amaterasu, Grian, Marici, Saulė, Sulis and Xihe as well as gods Amun, Apollo, Helios, Ra, Shamash, Surya, Tonatiuh and Utu; the gender of the Guanche solar deity Magec is unknown.
