These strong features of resemblance proceed, no doubt, from the imagination of the parents, over which we may reasonably believe that many casual circumstances have a very powerful influence; such, for instance, as the action of the eyes, the ears, or the memory, or impressions received at the moment of conception. A thought[990] even, momentarily passing through the mind of either of the parents, may be supposed to produce a resemblance to one of them separately, or else to the two combined. Hence it is that the varieties are much more numerous in the appearance of man than in that of other animals; seeing that, in the former, the rapidity of the ideas, the quickness of the perception, and the varied powers of the intellect, tend to impress upon the features peculiar and diversified marks; while in the case of the other animals, the mind is immovable, and just the same in each and all individuals of the same species.[991] A man named Artemon, one of the common people,[992] bore so strong a resemblance to Antiochus, the king of Syria, that his queen Laodice, after her husband Antiochus was slain, acted the farce of getting this man[993] to recommend her as the successor to the crown. Vibius, a member of the plebeian order,[994] and Publicius as well, a freedman who had formerly been a slave, so strongly resembled Pompeius Magnus in appearance as to be scarcely distinguishable from him; they both had that ingenuous countenance[995] of his, and that fine forehead,[996] which so strongly bespoke his noble descent. It was a similar degree of resemblance to this, that caused the surname of his cook, Menogenes, to be given to the father of Pompeius Magnus, he having already obtained that of Strabo, on account of the cast in his eye,[997] a defect which he had contracted through imitating a similar one in his slave. Scipio, too, had the name of Serapion given him, after the vile slave of a pig-jobber: and after him, another Scipio of the same family was surnamed Salvitto, after a mime[998] of that name. In the same way, too, Spinther and Pamphilus, who were respectively actors of only second and third rate parts, gave their names to Lentulus and Metellus, who were at that time colleagues in the consulship; so that, by a very curious but disagreeable coincidence, the likenesses of the two consuls were to be seen at the same moment on the stage.
