The Dragon-Horse (chin. Longma) is a horse-like dragon from chinese mythology. It has the body of a horse, but the scales and head of a chinese dragon, some also have wings. Emperor Mu of the Jin-Dynasty had a wagon that was drawn by eight winged dragon horses.
Because it combines the concepts of the sky (dragon) and the earth (horse), it is seen as an embodyment of both elements.
Dragon-horses are born by mares who drank from rivers inhabited by dragons.
