On the jambs of doorways in three of the Persepolitan buildings, a human figure, dressed in the Median robe, but with the sleeve thrown back from the right arm, is represented in the act of killing either a lion, a bull, or a grotesque monster. In every case the animal is rampant, and assails his antagonist with three of his feet, while he stands on the fourth. The lion and bull have nothing about them that is very peculiar; but the monsters present most strange and unusual combinations. One of them has the griffin head, which we have already seen in use in the capitals of columns, a feathered crest and neck, a bird’s wings, a scorpion’s tail, and legs terminating in the claws of an eagle. The other has an eagle’s head, ears like an ass, feathers on the neck, the breast, and the back, with the body, legs, and tail of a lion. [PLATE LV., Fig. 1.] Figures of equal grotesqueness, some of which possess certain resemblances to these, are common in the mythology of Assyria, and have been already represented in these volumes; but the Persian specimens are no servile imitations of these earlier forms. The idea of the Assyrian artist has, indeed, been borrowed; but Persian fancy has worked it out in its own way, adding, modifying, and subtracting in such a manner as to give to the form produced a quite peculiar, and (so to speak) native character. [Illustration: PLATE LV.] Persian gems abound with monstrous forms, of equal, or even superior grotesqueness. As the Gothic architects indulged their imagination in the most wonderful combinations to represent evil spirits or the varieties of vice and sensualism, so the Persian gem-engravers seem to have allowed their fancy to run riot in the creation of monsters, representative of the Powers of Darkness or of different kinds of evil, The stones exhibit the king in conflict with a vast variety of monsters, some nearly resembling the Persepolitan, while others have strange shapes unseen elsewhere. Winged lions, with two tails and with the horns of a ram or an antelope, sphinxes and griffins of half a dozen different kinds, and various other nondescript creatures, appear upon the Persian gems and cylinders, furnishing abundant evidence of the quaint and prolific fancy of the designers.
