Tuesday is the day of Mars. The word Tuesday comes from Old English Tīwesdæg, ‘day of Tīw,’ a Germanic god of war and the sky. The Latin translation is dies Marti, ‘day of Mars.’ The god Tīw was equated with the Roman god Mars.
In Roman mythology, a woodpecker was considered a sacred bird to Mars. This is the Ladderback Woodpecker, found in the Mojave Desert. Some Mojave plants associated with Mars are (Pinyon) Pine and (Desert Rock) Nettle.
