A god, goddess, or planet governs each day of the week. It is usually easy to spot the ruler of the day by its name. The word Tuesday, however, is not so easy, but if we look at the word in Spanish, Martes, we clearly see its connections to Mars.
Because Tuesday revolves around the energy of Mars, Tuesdays are good for business, mechanical things, buying and selling animals, hunting, beginning studies, gardening, sexual activities, and confrontation. This is a day for sex magick, energy, stamina, and health. As in the old saying, Tuesdays child is full of grace, is also good for success magick and defense against enemies.
Angels of Tuesday are Camael, Samael, Satael, Amabiel, Friagne, and Hyniel. When invoked, Camael takes the form of a leopard. In Druid mythology he is a god of war, which is why we see him associated with Mars. Camael is said to be a member of the “Magnificent Seven” in some circles. Camael is another “terminator” angel.
Samael walks both worlds as a magician and sorcerer. some see him as the angel of death, others as “the bright and poisonous one.” Many consider him more of a demon, and accuse him of being Satan. However, there is reference to the satans (plural) as enforcers of the law, a sort of angelic police, if you will. Supposedly, when Samael is around, dogs howl in the night. On one hand, he is the ruler of the fifth heaven and in charge of two million angels; on the other, he is the one who changed into a serpent and convinced Eve to partake of the forbidden fruit of knowledge.
Satael is an angel of air invoked in magic rites and is the presiding spirit of the planet Mars. Amabiel is another spirit of the planet Mars; however he spends his energy on issues of human sexuality. Friagne, also an angel of this day, is invoked from the east. He is a member of the fifth heaven. Hyniel also belongs to this day and is subject to the east wind.
On Tuesdays the hour of sunrise and every eight hours after that are also ruled by Mars, and that makes these times of the day doubly blessed. These four hours are the strongest ones to do ritual in. Check your local newspaper, astrological calendar, or almanac to determine your local sunrise.
