History and myth

The Bull is Zeus in the form that carried Europa to Crete. Its face is outlined by the Hyades cluster and the Pleiades ride on its shoulder — both visible to the naked eye. Red Aldebaran seems to belong to the Hyades but lies half as far away and merely falls along the same line of sight.
