Centaurs are half-human, half-horse creatures in Greek mythology. They have the body of a horse and the torso, head and arms of a man. They were considered to be the children of Ixion, king of the Lapiths, and Nephele, a cloud made in the image of Hera.
The figurative and literal language of the poem shows and descibes a ten year old girl playing. Swenson uses the Greek mythological creature, the Centaur, as a symbol of the girl pretending to ride the horse. A centaur is half-man half-horse creature. Itâs neck and head is human while the body is that of a horse. In describing the girl riding her Stick pony, Swenson makes it seem as though the girl herself is a Centaur.
