Happy to share my article that compares uses of tekmêrion (proof or convincing proof) by Herodotus and Luke in relation to their beliefs--which were obviously different--that the divine was at work in the scenes they describe.
The article can be found here (if you have access):
Proofs of the Divine: Luke’s Use of Tekmhpion in Acts 1:3 in Light of Herodotus’ Description of the Battle of Mycale (Hist. 9.100.2): Here is the abstract:
In Acts 1:3, the author claims that Jesus had shown himself alive ‘by many proofs’ (ἐν πολλοῖς τεκμηρίοις). Phrases containing τεκμήριον (a NT hapax) qualified by πολύς have a long textual history. Reference works, however, do not discuss the closest rhetorical and theological parallel to the occurrence of τεκμήριον in Acts, which is found in Herodotus’ description of the battle of Mycale (Histories 9.100.2) in a metaleptic aside about proofs of divine intervention in human history: Δῆλα δὴ πολλοῖσι τεκμηρίοισι ἐστὶ τὰ θεῖα τῶν πρηγμάτων. Given the theologically charged nature of Luke–Acts and the Histories, this rich parallel illustrates well both projects and evinces plausible Herodotean influence on Luke’s historiographical erudition.
