Taurus marked the point of vernal (spring) equinox in the Chalcolithic and the Early Bronze Age, from about 4000 BC to 1700 BC, after which it moved into the neighboring constellation Aries. The Pleiades were closest to the Sun at vernal equinox around the 23rd century BC.
In Babylonian astronomy, the constellation was listed in the MUL.APIN as GU4.AN.NA, “The Bull of Heaven”. As this constellation marked the vernal equinox, it was also the first constellation in the Babylonian zodiac and they described it as “The Bull in Front”. The Akkadian name was Alu.
Aleph is the first letter of the Semitic abjads, including Phoenician ‘Ālep Phoenician aleph.svg, Hebrew ‘Ālef א, Aramaic Ālap Aleph.svg, Syriac ʾĀlap̄, Arabic Alif ا, and Persian.
The Phoenician letter is derived from an Egyptian hieroglyph depicting an ox’s head and gave rise to the Greek Alpha (Α), being re-interpreted to express not the glottal consonant but the accompanying vowel, and hence the Latin A and Cyrillic А.
