Pliny the Elder, HN 36.41 (ca. A.D. 65): Inhonorus est nec in templo ullo Hercules, ad quem Poeni omnibus annis humana sacrificaverant victima, humi stans ante aditum porticus ad nationes. Sitae fuere et Thespiades ad aedem Felicitatis, quarum unam amavit eques Romanus Iunius Pisciculus, ut tradit Varro, admirator et Pasitelis, qui et quinque volumina scripsit nobilium operum in toto orbe. Natus hic in Graeca Italiae ora et civitate Romana donatus cum iis oppidis, Iovem fecit eboreum in Metelli aede, qua campus petitur. Accidit ei, cum in navalibus, ubi ferae Africanae erant, per caveam intuens leonem caelaret, ut ex alia cavea panthera erumperet, non levi periculo diligentissimi artificis. Fecisse opera complura dicitur; quae fecerit, nominatim non refertur. Arcesilaum quoque magnificat Varro, cuius se marmoream habuisse leaenam aligerosque ludentes cum ea Cupidines, quorum alii religatam tenerent, alii cornu cogerent bibere, alii calciarent soccis, omnes ex uno lapide. Idem a Coponio quattuordecim nationes, quae sunt circa Pompeium, factas auctor est. A work that is without honor and stands in no temple is the Hercules before which the Carthaginians were wont to perform human sacrifices every year.  This stands at ground-level in front of the entrance to the Portico of the Nations. Formerly too there were statues of the Muses of Helicon by the temple of Prosperity, and a Roman knight, Junius Pisciculus, fell in love with one of them, according to Varro, who incidentally was an admirer of Pasiteles, a sculptor who was also the author of a treatise in five volumes on the World's Famous Masterpieces.  He was a native of Magna Graecia and received Roman citizenship along with the communities of that region.  The ivory Jupiter in the temple of Metellus at the approaches to the Campus Martius is his work. Once, he was at the docks, where there wild beasts from Africa, and was making a relief of a lion, peering as he did so into the cage of his model, when it so happened that a leopard broke out of another cage and caused serious danger to this most conscientious of artists.  He is said to have executed a number of works, but their titles are not recorded.  Arcesilaus too is highly praised by Varro, who states that he once possessed a work of his, namely Winged Cupids Playing with a Lioness, of whom some were holding it with cords, some were making it drink from a horn, and some were putting slippers on its feet, all the figures having been carved from one block.  Varro also relates that it was Coponius who was responsible for the fourteen figures of the Nations which stand around Pompeius' theater.  (H.
