The most extreme consequence for any type of human activity is death: and such an unfortunate event has often occurred through coitus. Death during sexual activity was noted by Pliny A.D. 23-79, Hirschfeld, Van de Velde, Havelock Ellis, etc. It has been suggested that some Oriental copulations have been pursued with the very aim of totally exhausting, or even killing, the woman - the Japanese gokuraku-ojo or "sweet death". According to Muhammed, to die in the glorious battle abed with one's belly on top is to die a martyr of love. The Caliph Harun er-Reshid was reckoned a hero because he died of heart failure during sexual intercourse. Christian sages have viewed things differently, seeing death in coitus as a final infamy. Attila the Hun was said to have died fornicating with a blonde.
