The birth of conjoined twins has always fascinated mankind, with the public’s view of malformed children greatly influenced by the prevailing culture and religious beliefs. In prehistoric times, conjoined twins were depicted in cave drawings, on pottery, or as figurines. In folklore, they were often regarded as an omen of impending disaster, eliciting strong emotions ranging from wonder and admiration to rejection and hostility. Although malformed children were treated compassionately at times, historical records show that infanticide was frequently practiced and the mother was often held responsible for causing the malformation.
