Myth

The ram with the golden fleece rescued Phrixus and Helle from their stepmother; its fleece, hung in a sacred grove, was what the Argonauts went to steal.

History

Precession has since carried the spring equinox into Pisces, but astronomers and astrologers still call it the First Point of Aries.

Look for

Three stars in a bent line — Hamal, Sheratan and Mesarthim. Mesarthim is a pretty equal double in any small telescope.
