Another important group of subjects is concerned with Herakles’ adventures with the Centaurs, which fall under several headings. Allusion has already been made to his early education by Cheiron, and again we see him paying a visit of a peaceful nature to the aged Pholos, who entertains him by opening a jar of wine.[1157] The smell therefrom attracted the other Centaurs and led to a combat, which we see vividly depicted on many early B.F. vases, on which it was a favourite subject, as also on later ones.[1158] We also find him in combat with particular Centaurs, from whom he rescues a woman carried off by them. Thus we see Hippolyta delivered from Eurytion,[1159] and Deianeira from Nessos[1160] or Dexamenos[1161] (the latter appears on later vases only, and there seems to be no distinction between them in the myth). Other adventures in which he engages include the freeing of Prometheus from the vulture, which he slays with his bow[1162]; the bringing back of Alkestis from Hades[1163]; the seizure of the Kerkopes, a pair of brigands, whom he carries off head downwards over his shoulders[1164]; and his capture by Busiris in Egypt,[1165] with his escape after slaying the king’s negro attendants.[1166] Among rarer myths may be mentioned the destruction of the vines of Syleus[1167]; a possible representation of his contest in drawing water with Lepreos[1168]; and his combat with Erginos, the king of Orchomenos, and the capture of his heralds.[1169] A vase in Athens, on which he is depicted dragging two Satyrs in a leash,[1170] depicts an unknown myth; as do those which represent him contending with Geras, a personification of Old Age,[1171] and beating a winged Ker with his club.[1172] In company with Athena he attacks an unknown man,[1173] and he is also seen leading a Sphinx.[1174]
