Percy Gardner, in the discussion of the date of this artist,[2100] has shown how slight is the evidence for any date later than 320 B. C. The date of the second Olympic victory of Cheilon of Patrai, whose statue was by Lysippos, can not be later than 320 B. C.[2101] Pausanias quotes the inscription on the base of the statue to the effect that Cheilon died in battle and was buried for his valor’s sake by the Achæan people. He infers the date of his death by reference to the date of Lysippos as either 338 B. C. (Chæroneia) or 322 B. C. (Lamia). In another passage, VII, 6.5, he says that the Olympic guide told him that Cheilon was the only Achæan who fought at Lamia. Gardner justly remarks that either of these dates, the two occasions in the lifetime of Lysippos when the Achæans took part in an important war, fall within the dates of the artist’s activity.[2102] The dates of the two hoplite victories of Kallikrates of Magnesia, on the Meander, whose statue was also the work of Lysippos, must be left indeterminate.[2103] Gardner also shows that the wish not to separate Lysippos from the _Apoxyomenos_ has been the real reason which has influenced so many archæologists to extend his activity to the end of the fourth century,[2104] and to explain away the evidence for an earlier date offered by the statue of Troilos, who won his second victory in 368 B. C. If we once for all give up the _Apoxyomenos_, the difficulty of an early dating disappears, as does also the theory that Skopas could have strongly influenced the youthful Lysippos as a master would influence a pupil, and it becomes clear that this influence must have been mutual, that of one great contemporary upon another. Although Lysippos worked longer, as is attested by his work for Alexander and his generals, he could have been but little if any younger than either Skopas or Praxiteles, from both of whom he learned. We have already quoted Homolle[2105] as saying that an analysis of the style of the _Agias_ discloses the mixed influences of Praxiteles and Skopas, as well as the independent work of Lysippos, in the pose, proportions, and whole type of the figure.
