Myths and Legends of Ancient Greece and Rome 

Before entering upon the many strange beliefs of the ancient Greeks, and the extraordinary number of gods they worshipped, we must first consider what kind of beings these divinities were. In appearance, the gods were supposed to resemble mortals, whom, however, they far surpassed in beauty, grandeur, and strength; they were also more commanding in stature, height being considered by the Greeks an attribute of beauty in man or woman. They resembled human beings in their feelings and habits, intermarrying and having children, and requiring daily nourishment to recruit their strength, and refreshing sleep to restore their energies. Their blood, a bright ethereal fluid called Ichor, never engendered disease, and, when shed, had the power of producing new life.
