Puzzle ID: 01-11/2017 'Punchy'

The Problem:
The two photographs below show the base of a Roman bronze statuette, now on sale at a London antiquities dealer, with a punched inscription of which the last two words can be read as Ἡρακλεῖ εὐχήν (εὐχήν written around the base only visible in the second photograph).

Question:
Can anyone help with identifying the text before Ἡρακλεῖ εὐχήν?
