AMALTHEIA, in Greek mythology, the foster-mother of Zeus.
This goat having broken off one of its horns, Amaltheia filled it with flowers and fruits and presented it to Zeus, who placed it together with the goat amongst the stars.
According to another story, Zeus himself broke off the horn and gave it to Amaltheia, promising that it would supply whatever she desired in abundance.
Amaltheia gave it to Achelous (her reputed brother), who exchanged it for his own horn which had been broken off in his contest with Heracles for the possession of Deianeira.
The term "horn of Amaltheia" is applied to a fertile district, and an estate belonging to Titus Pomponius Atticus was called Amaltheum.
