Histories

Such were the gifts which he sent to Delphi [22.5167,38.4917] (Perseus) Delphi. To Amphiaraus, of whose courage and fate he had heard, he dedicated a shield made entirely of gold and a spear all of solid gold, point and shaft alike. Both of these were until my time at Thebes [23.3333,38.325] (Perseus) Thebes, in the Theban temple of Ismenian Apollo.

The Lydians who were to bring these gifts to the temples were instructed by Croesus to inquire of the oracles whether he was to send an army against the Persians and whether he was to add an army of allies.
