Erasmus

god of love, late 14c., from Greek eros (plural erotes), "god or personification of love; (carnal) love," from eran, eramai, erasthai "to desire," which is of uncertain origin. Beekes suggests it is from Pre-Greek.

The Freudian sense of "urge to self-preservation and sexual pleasure" is from 1922. Ancient Greek distinguished four ways of love: erao "to be in love with, to desire passionately or sexually;" phileo "have affection for;" agapao "have regard for, be contented with;" and stergo, used especially of the love of parents and children or a ruler and his subjects.
