visible cause for the law of gravitation not acting upon it, is an absurdity of which no example can be found in the old works of art. It is not allowable even in modern painting. If a body is to be suspended in the air, it must either have wings or appear to rest upon something, if only a cloud. When Homer makes Thetis rise on foot from the sea-shore to Olympus, Τὴν μὲν ἄρ’ Οὔλυμπον δὲ πόδες φέρον (Iliad, xviii. 148), Count Caylus is too well aware of the limitations of art to counsel the painter to represent her as walking unsupported through the air. She must pursue her way upon a cloud (Tableaux tirés de l’Iliade, p. 91), as in another place he puts her into a chariot (p. 131), although exactly the opposite is stated by the poet. How can it be otherwise? Although the poet represents the goddess with a human body, he yet removes from her every trace of coarse and heavy materiality, and animates her with a power which raises her beyond the influence of our laws of motion. How could painting so distinguish the bodily shape of a deity from the bodily shape of a human being, that our eyes should not be offended by observing it acted upon by different laws of motion, weight, and equilibrium? How but by conventional signs, such as a pair of wings or a cloud? But more of this elsewhere; here it is enough to require the defenders of the Addison theory to show on the old monuments a second figure floating thus unsupported in the air. Can this Mars be the only one of its kind? why? Were there some particular conditions handed down by tradition which would necessitate such exceptional treatment in this one case? There is no trace of such in Ovid (Fast. lib. i.), but rather proof that no such conditions ever could have existed. For in other ancient works of art which represent the same story, Mars is evidently not hovering, but walking. Examine the bas-relief in Montfaucon (Suppl. T. i. p. 183), which is to be found, if I am not mistaken, in the Mellini palace at Rome. Rhea lies asleep under a tree, and Mars approaches her softly, with that expressive backward motion of the right hand by which we warn those behind to stay where they are, or to advance gently. His attitude is precisely the same as on the coin, except that in one case he holds his lance in the right, in the other in the left hand. We often find famous statues and bas-reliefs copied on coins, and the same may well be the case here, only that the cutter of the die did not perceive the force of the backward motion of the hand, and thought it better employed in holding the lance. Taking all these arguments into consideration, what degree of probability remains to Addison’s theory? Hardly more than a bare possibility. But where can better explanation be had if this fails? Possibly among the interpretations rejected by Addison. But if not, what then? The passage in the poet is corrupted, and so it must remain. It certainly will so remain, if twenty new conjectures are invented.
