incedo per ignes
Suppositos cineri doloso.
Hor.
And perhaps I am not the first discoverer of his faults: yet I do not remember to have seen any thing relative to them.
The Diomedes of Dioscorides is either a sitting, or a rising figure; for the attitude is ambiguous. It is plain he is not sitting; and rising is inconsistent with his action.
Our body endeavouring to raise itself from a seat, moves always mechanically towards its sought-for centre of gravity, drawing back the legs, which were advanced in sitting[26]; instead of which the figure stretches out his right leg. Every erection begins with elevated heels, and in that moment all the weight of the body is supported only by the toes, which was observed by Felix[27], in his Diomedes: but here all rests on the sole.
Nor can Diomedes, (if we suppose him to be a sitting figure, as he touches with his left leg the bottom of his thigh) find, in raising himself, the centre of his gravity, only by a retraction of his legs, and of course cannot rise in that posture. His left hand resting upon the bended leg, holds the palladion, whilst his right touches negligently the pedestal with the point of a short sword; consequently he cannot rise, neither moving his legs in the natural and easy manner required in any erection, nor making use of his arms to deliver himself from that uneasy situation.
There is at the same time a fault committed against the rules of perspective.
The foot of the left bended leg, touching the cornice of the pedestal, shews it over-reaching that part of the floor, on which the pedestal and the right foot are situated, consequently the line described by the hinder-foot is the fore on the gem, and vice versa.
But allowing even a possibility to that situation, it is contrary to the Greek character, which is always distinguished by the natural and easy. Attributes neither to be met with in the contortions of Diomedes, nor in an attitude, the impossibility of which every one must be sensible of, in endeavouring to put himself in it, without the help of former sitting.
