The Second Decan of Aries

This is the second ten-degree segment of Aries, the cardinal fire sign, spanning 10 to 20 degrees. Its ruler in the Chaldean order of faces, the scheme used on this site, in which the seven visible planets are assigned to the thirty-six decans in sequence from Mars at zero Aries, is the Sun. The decans themselves are the oldest layer of this material: they began as thirty-six Egyptian star groups whose successive risings marked the ten-day weeks of the year and the hours of the night, and were only later absorbed into the Greek zodiac as ten-degree subdivisions of the signs and given planetary rulers.

The Golden Dawn, from 1888, mapped the thirty-six numbered minor cards onto the decans in order; this segment carries the Three of Wands, to which they gave the title Virtue, the planet taken directly from its Sun-ruled face. That tarot layer is a modern Western overlay, not part of the ancient decan tradition.
