<P> He spent most of the time in his dark realm . Formidable in battle, he proved his ferocity in the famous Titanomachy, the battle of the Olympians versus the Titans, which established the rule of Zeus . </P> <P> Feared and loathed, Hades embodied the inexorable finality of death: "Why do we loathe Hades more than any god, if not because he is so adamantine and unyielding?" The rhetorical question is Agamemnon's . He was not, however, an evil god, for although he was stern, cruel, and unpitying, he was still just . Hades ruled the Underworld and was therefore most often associated with death and feared by men, but he was not Death itself--the actual embodiment of Death was Thanatos, although Euripides' play "Alkestis" states fairly clearly that Thanatos and Hades were one and the same deity, and gives an interesting description of him as dark - cloaked and winged; moreover, Hades was also referred to as "Hesperos Theos" ("God of Death and Darkness"). </P> <P> When the Greeks propitiated Hades, they banged their hands on the ground to be sure he would hear them . 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 . 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 . </P> <P> 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 . In certain portraits, snakes also appeared to be attributed to Hades 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 . 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 . Zeus Meilichios and Zeus Eubouleus are often referred to being alternate names for Hades . </P>
