Chest of Kypselos from temple of Hera at Olympia (known through Pausanias’ description and modern reconstructions)
Pausanias Description of Greece 5.17.11:
Iolaus, who voluntarily helped Heracles in his labours, is shown as a victor in the chariot-race [or as Heracles’ helper]. At this point the funeral games of Pelias come to an end, and Heracles, with Athena standing beside him, is shooting at the hydra, the beast in the river Amymone. Heracles can be easily recognized by his exploit and his attitude, so his name is not inscribed by him (original Greek).
Detail with Herakles and Hydra, from reconstruction of chest of Kypselos by W. von Massow, “Die Kypseloslade,” Mitteilungen des Deutschen Archäologischen Instituts, Athenische Abteilung vol. 41 (1916), 1 ff., pl. 10.
Throne of Apollo at Amyklai (known through Pausanias’ description and modern reconstructions)
Pausanias Description of Greece 3.18.13:
