Leonardo's Dragon

I came across this quote from Leonardo DaVinci's "How to Make an Imaginary Animal Appear Real":

If therefore you wish to make one of your imagined animals appear natural—let us suppose it to be a dragon—take for its head that of a mastiff or setter, for its eyes those of a cat, for its ears those of a porcupine, for its nose that of a greyhound, with the eyebrows of a lion, the temples of an old cock, and the neck of a water tortoise.

Something about that passage had a familiar ring to it, and I finally figured out why:

And the shapes of the locusts were like unto horses prepared unto battle; and on their heads were crowns like gold, and their faces were as the faces of men. And they had hair as the hair of women, and their teeth were as the teeth of lions. And they had breastplates, as it were breastplates of iron; and the sound of their wings was as the sound of chariots of many horses running to battle. And they had tails like unto scorpions, and there were stings in their tails: and their power was to hurt men five months. And they had a king over them, which is the angel of the bottomless pit, whose name in the Hebrew tongue is Abaddon, but in the Greek tongue hath his name Apollyon (Revelation. 9: 7-11).

Does one illuminate the other? I shall have to ponder this . . .
