The first variable star to be discovered was Omicron Ceti. In 1596 the German astronomer David Fabricius (1564-1617) noticed its changing light intensity.
Omicron Ceti, the prototype Mira star, revealed itself to the Hubble Space Telescope as an irregular blob about 60 milliarcseconds wide.
Even the two Fishes of Pisces were in the Mesopotamian sky, but under the title "The Tails"--presumably because the two cords from the Fishes to the Knot Star (probably our Mira, Omicron Ceti) are tied to their tails.
