But to return from this digression to the consideration of the passage by Pliny relating to portraiture in modeling and sculpture. In the sentence immediately following, Pliny goes on to say, “Idem et de signis effigiem exprimere invenit, crevitque res in tantum, ut nulla signa statuæve sine argilla fierent,”—Lysistratus also made copies from statues, and this practice came so into vogue that no statues in brass or marble were made without white clay. What the meaning of this sentence is we can only guess; as it stands, it is quite unintelligible. Perhaps he intended to say that Lysistratus set the fashion of making small copies in clay or terra cotta of all the statues that were executed. But it is quite possible that he meant nothing of the kind. It is plain that if Lysistratus had already invented casting in plaster, it would have been unnecessary to copy statues in clay, except for the purpose of reduction to statuettes. Mr. Perkins thinks he may have intended to speak of “esquisses d’argile [maquettes] dont se servent les sculpteurs comme point de départ, esquisse reproduite plus tard en marbre et avec la mise aux points.” But there was nothing new in this; and surely Lysistratus could not be said to have invented, or set the fashion of, a process which certainly had been employed very long before his time. And again, why make a small statue in clay and enlarge it proportionally in marble, if you can make it at once in full size and cast it? Nor does Mr. Perkins seem to be aware that in adopting this view, and translating as he does “de signis effigiem exprimere,”—to make a small model or maquette in clay,—he abandons his explanation of the sentence referring to gypsum. For if “effigiem argilla exprimere” means, as he says, to make a model in clay, why does not “imaginem gypso exprimere” mean to make a model in plaster? Besides, the fact that Pliny applies the same terms to a process in clay as to one in plaster at once puts an end to the matter so far as the question of casting goes. Clay is not a material to cast with, in any proper sense of that term. Another objection to this interpretation that Pliny meant a maquette, “esquisse,” or sketch is that “effigies” did not mean sketch. It carried with it nearly the significance of our own word effigy,—of great reality of imitation. “Imago” was a vaguer word, and might indicate a delusive resemblance as by painting; but “effigiem” was ordinarily employed to designate a more absolute imitation. Thus Cicero says, “Nos vere juris germanæ justitiæ que solidam et expressam effigiem nullam tenemus. Umbra et imaginibus utimur.”[12] And again, “Consectatur nullam eminentem effigiem virtutis sed adumbratam imaginem gloriæ.” “Effigies” would, therefore, carry no such idea as that of sketch.
