The Sire-Bond...

When the Greeks propitiated Hades, they banged their hands on the ground to be sure he would hear them.[33] Black animals, such as sheep, were sacrificed to him, and the very vehemence of the rejection of human sacrifice expressed in myth suggests an unspoken memory of some distant past.[citation needed] The blood from all chthonic sacrifices including those to propitiate Hades dripped into a pit or cleft in the ground. The person who offered the sacrifice had to avert his face.[34] One ancient source says that he possessed the Cap of invisibility. His chariot, drawn by four black horses, made for a fearsome and impressive sight. His other ordinary attributes were the narcissus and cypress plants, the Key of Hades and Cerberus, the three-headed dog.[35] In certain portraits, snakes also appeared to be attributed to Hades[36] as he was occasionally portrayed to be either holding them or accompanied by them. This is believed to hold significance as in certain classical sources Hades ravished Kore in the guise of a snake, who went on to give birth to Zagreus-Dionysus[37]. While bearing the name 'Zeus', Zeus Olympios, the great king of the gods, noticeably differs from the Zeus Meilichios, a decidedly Chthonian character, often portrayed as a snake, and as seen beforehand, they cannot be different manifestations of the same god, in fact whenever 'another Zeus' is mentioned, this always refers to Hades[38]. Zeus Meilichios and Zeus Eubouleus are often referred to being alternate names for Hades[39].
