The constellation that is referred to as "rams" is Aries.
In Greek mythology, Aries represents the golden ram that rescued the siblings Phrixus and Helle from being sacrificed by their stepmother.
The ram carried the siblings away to a distant land, but Helle fell off and drowned in the sea, which is why the area where she fell became known as the Hellespont.
In some cultures, Aries is also associated with the ram-headed god of fertility and rebirth, which may have led to the reference to "rams".
