Aries (meaning: "ram") is one of the constellations of the zodiac, located between Pisces to the west and Taurus to the east. Its name is Latin for ram, and its symbol is Aries.svg (Unicode ♈), representing a ram's horns. Aries was one of the 48 constellations described by the 2nd century astronomer Ptolemy, and remains one of the 88 modern constellations today.

Ancient Greek astronomers visualized Aries as a ram lying down with its head turned to the right. The stars α, β and γ Arietis mark the ram’s head and horns, according to Ptolemy's Almagest.


In the ancient Babylonian calendar given in the stone tablets known as the MUL.APIN, the constellation now known as Aries was the final station along the ecliptic. It was known as MULLU.ḪUN.GA, "The Agrarian Worker". It is unclear how the "Agrarian Worker" became the "Ram" of Greek tradition, but John H. Rogers has suggested that it may have been via association with the legendary figure of Dumuzi the Shepherd. Aries only rose to its prominent position in the Neo-Babylonian revision of the Babylonian zodiac as the first point of Aries came to represent vernal equinox, replacing the Pleiades which had had this function during the Bronze Age.[1]

In Greek mythology, the constellation of Aries represents the golden ram that rescued Phrixos, taking him to the land of Colchis. Phrixos sacrificed the ram to the gods and hung its skin in a temple, where it was known as the Golden Fleece.[2]


As of 2009, the Sun appears in the constellation Aries from April 19 to May 13. In tropical astrology, the Sun is considered to be in the sign Aries from March 21 to April 19, and in sidereal astrology, from April 15 to May 15.
