Labels:text | letter | paper | ink | document OCR: This monster was likely a conception for a costume design for a court entertainment. Two men would crouch inside, walking with bent legs to propel the dragon forward. Leonardo advised that imaginary beasts be drawn in a composite fashion: "If you wish to make an animal, imagined by you, appear natural-let us say a dragon-take for its head that of a mastiff or hound, with the eyes of a cat, the ears of a porcupine, the nose of a greyhound, the brow of a lion, the A Dragon temples of an old cock, the neck of a water tortoise." ca. 1515-17, black chalk and pen and ink 7 3/8 x 10 /e in.
