Babylon

According to Archer Taylor, "the oldest recorded riddles are Babylonian school texts which show no literary polish". The answers to the riddles are not preserved; the riddles include "my knees hasten, my feet do not rest, a shepherd without pity drives me to pasture" (a river? A rowboat?); "you went and took the enemy's property; the enemy came and took your property" (a weaving shuttle?); "who becomes pregnant without conceiving, who becomes fat without eating?" (a raincloud?). These may be riddles from oral tradition that a teacher has put into a schoolbook.
