The brightest star of Aries (α) is sometimes called Hamal, derived from the Arabic _al-hamal_, a name given to the constellation itself by Al-Sufi. In the Accadian language it was called _Dilkur_, "the dawn proclaimer." Ali-Sufi says that close to α, "as if it were attached to it," is a small star of the 6th magnitude, not mentioned by Ptolemy. This is clearly κ Arietis. The fact of Al-Sufi having seen and noticed this small star, which modern measures show to be below the 5th magnitude, is good evidence of his keen eyesight and accuracy of observation. According to Al-Sufi, the stars β and γ Arietis were called by the Arabians _al-scharatain_, "the two marks." They marked the "first mansion of the moon," and ε, δ, and ρ the second mansion. With reference to these so-called "mansions of the moon," Admiral Smyth says-- "The famous _Manazil al-kamar_, i.e. Lunar mansions, constituted a supposed broad circle in Oriental astronomy divided into twenty-eight unequal parts, corresponding with the moon's course, and therefore called the abodes of the moon. This was not a bad arrangement for a certain class of gazers, since the luminary was observed to be in or near one or other of these parts, or constellations every night. Though tampered with by astrologers, these Lunar mansions are probably the earliest step in ancient astronomy."[402] Taurus, the second constellation of the Zodiac, was in ancient times represented by the figure of a bull, the hinder part of which is turned towards the south-west, and the fore part towards the east. It had no hind legs, and the head was turned to one side, with the horns extended towards the east. Its most ancient name was _Te_, possibly a corruption of the Accadian _dimmena_, "a foundation-stone." The Greek name is αθωρ (θωωρ, Eusebius). In the old Egyptian mythology Taurus represented the god Apis. According to Dupuis it also represented the 10th "labour of Hercules," namely, his victory over the cows of Geryon, King of Spain.[403] It was also supposed to represent the bull under the form of which Jupiter carried off Europa, daughter of Agenor, King of the Phœnicians. It may also refer to Io or Isis, who is supposed to have taught the ancient Egyptians the art of agriculture.
