Pliny the Elder, HN 34.57 (ca. A.D. 65): Myronem Eleutheris natum, Hageladae et ipsum discipulum, bucula maxime nobilitavit celebratis versibus laudata, quando alieno plerique ingenio magis quam suo commendantur. Fecit et Ladam et discobolon et Peseum et pristas et Satyrum admirantem tibias et Minervam, Delphicos pentathlos, pancratiastas, Herculem, qui est apud circum maximum in aede Pompei Magni. Myron who was born at Eleutherae, was himself also a pupil of Hagelades; he was specially famous for his statue of a heifer, celebrated in some well-known sets of verses—inasmuch as most men owe their reputation more to someone else's talent than to their own. His other works include Ladas and a "Discobolos" or Man Throwing a Discus, and Perseus, and The Sawyers, and the Satyr Marvelling at the Flute and Athene, Competitors in the Five Bouts at Delphi, the All-Round Fighters, and the Hercules now in the temple of Pompeius Magnus at the Circus Maximus.  (H.
