Parallels in Babylonian Legends.

The "bull of heaven" probably refers to some legend such as that of the story of Gilgameš in his conflict with the goddess Ištar when the divine bull was killed; /Sib-zi-anna/, "the faithful shepherd of heaven," suggests that this constellation may refer to Tammuz, the divine shepherd; whilst "the scorpion" reminds us of the scorpion-men who guarded the gate of the sun (Šamaš), when Gilgameš was journeying to gain information concerning his friend Enki-du, who had departed to the place of the dead. Sir Henry Rawlinson many years ago pointed out that the story of the Flood occupied the eleventh tablet of the Gilgameš series, corresponding with the eleventh sign of the Zodiac, Aquarius, or the Water-bearer.
