[1] Eusebius of Caesarea lists Chionis as victor in both the stadion and diaulos races at the 29th, 30th and 31st Olympiads (conventionally dated 664–656 BC).

[2] Pausanias' Description of Greece credits Chionis with a fourth stadion victory in the 28th games of 668 BC, which Eusebius assigns to Charmis of Sparta.

[1] Chionis' record number of Olympic victories was not matched until 480 BC, when Astylos of Croton (representing Syracuse in Sicily) won his third stadion–diaulos double and added a seventh victory by winning the hoplitodromos, a race run in hoplite armour.

[9] Eusebius, probably quoting Sextus Julius Africanus, says Chionis could jump a distance of 52 podes (feet).

[10] Frank Zarnowski gives the Olympic foot a value of 32.05 cm, so that Chionis's mark of 16.66 metres (54.7 ft) is longer that the 55 podes achieved by Phayllos of Croton at the Pythian Games — 16.30 metres (53.5 ft) with a Pythian foot of 29.65 cm.
