Ram of the Zodiac
(The). This is the famous Chrysomallon, whose golden fleece was stolen by Jason in his Argonautic expedition. It was transposed to the stars, and made the first sign of the Zodiac.
The Vernal signs the Ram begins; Then comes the Bull; in May the Twins: The Crab in June; next Leo shines; And Virgo ends the northern signs. E. C. B.
