Book excerpt: Like their Western and Chinese counterparts, Native Americans developed an astrological system for understanding the world and envisioning harmony in the universe. Based on animals and clans--and with corresponding trees, stones, and colors--it’s broken into 12 moons similar to the 12 signs in Western astrology. In fascinating detail, and with magnificent artwork throughout, this new entry in the Simply series explores an exciting and little known aspect of Native culture. In addition to providing analyses of all the signs, symbols, and seasonal associations, there are illuminating charts, explanations of the medicine wheel, and practical ideas for using Native astrology as an oracle.
