"They thought the SHEEP would follow the STARS."
I think the Owl/Y head is related to Hyades/Taurus.
"Follow the Owl/Y head around the world."
It it these stars that would have been very important to early civilizations because they held the key to unlocking the rains of the heavens. "The Rain Makers."

"The Bull plays a splendid part in the Greek mythology. It was under this form that Jupiter carried Europa into Crete, and thereby gave the name of Europe to one of the quarters of the Earth."
The Taurus constellation is for the most part composed of two main groups of stars; the Pleiades and Hyades. Both groups have connections to rain; pluvial, a word related to Pleiades is a Latin term for rain; and hyein, a Greek term meaning 'to rain' is related to the word Hyades….
The word 'bull' is from the Indo-European root *bhel-2 'To blow, swell'.
from peleiades, flock of doves, from Indo-European *pel-2 'Pale, dark-colored, gray', 'the gray bird'.
Doves, peleiades (pel-2), have associations with the 'holy Spirit' or 'holy Ghost' which is a translation of Greek pneuma (pleu-).
Hyades: The other cluster of stars in Taurus form the face or forehead of the bull, are called the Hyades, and were put there to commemorate the sister's mourning of their brother Hyas who was the first-born of the Hyades. The Hyades lived on Mount Nysa and nurtured the infant Bacchus/Dionysus (God of wine; wine is from grapes). The word comes from Greek Huades, probably from Hys meaning 'pig'. In ancient Greek the Hyades cluster of stars were 'the rain-bringers' from hyein, 'to rain'; so called because the wet weather begins when they set. Aldebaran, the alpha star marking the left eye of the bull was sometimes included with the Hyades, and was called a 'Sow'; the colloquial title among the Roman country-people for the Hyades was Suculae, 'the Little Pigs', from Sus, 'Sow'. It was said that the title might come from the resemblance of this group of stars to a pig's jaws; or because Aldebaran and its companion stars were like a sow with her litter. Pliny accounting for it by the fact that the continual rains of the season of their setting made the roads so miry that these stars seemed to delight in dirt, like swine [Allen, Star Names, p.388.].
Hyades comes from the Indo-European root *su- 'Pig'.
Derivatives: swine, hog, Hogan, Hogg, Kellogg, socket, sow², soil², Hyades, hyena. [Pokorny su-s 1038. Watkins]
Hyades was Suculae, 'the Little Pigs'. Pokorny says su- is probably a derivative of seue-2
Derivatives: suck, soak, suction. [Pokorny 1. seu- 912. Watkins]
"Callistratus claims the Jews honored the pig because it is from this animal that the Jews learned how to plow the land, witnessing a hog dig his snout into the earth. He further states this explains the relation between the words hynis (”ploughshare”) and swine." http://framingbusiness.net/2006/why-do-the-jews-abstain-from-pork/ …
The astrological influences given by Manilius for the Hyades:
"The Hyades are a stormy star group and was regarded as a separate constellation. Those born at this time take no pleasure in tranquillity and set no store by a life of inaction; rather they yearn for crowds and mobs and civil disorders. Sedition and uproar delight them; they long for the Gracchi to harangue from the platform, for a secession to the Sacred Mount, leaving but a handful of citizens at Rome; they welcome fights which break the peace and provide sustenance for fears. They herd their foul droves over untilled countryside, for this constellation also begot Ulysses' trusty swineherd (Eumaeus, or Eumaios, was Odysseus' swineherd ). Such are the qualities engendered by the Hyades at the rising of their stars".
