Being the Cupid of the Greeks, Eros was known to be the most beautiful of all the immortal Gods. Considering that he was Aphrodite’s son, that was not really surprising. Eros carried lead and gold arrows that were strong enough to weaken the will of even the mightiest of Gods. Anyone struck by a Golden arrow would fall madly in love with the first woman he sees. The lead arrows did the exact opposite of the golden ones causing hatred towards a person.
It was Eros' arrow that stuck Helen of Troy, the most beautiful Grecian woman, causing her fall to in love and leaves her husband, Menelaos, for the city Troy. It was this sole act of blind love that began the infamous Trojan War. After the war Helen left Alexandros, her lover, and returned to her husband claiming her love affair was an act of Eros .
Eros was often depicted blindfolded, backing up the fact that love is blind.
