The inscription on a bronze mirror from Olbia mentioning the name Δημώνασσα (IGDOlb 92) and an unpublished letter on a lead plate with a fragmented author’s name [– – –]ώνασσα, probably, belong to one person, Demonassa Lenaio (Δημώνασσα Ληναίοˉ), who lived in 480-380 BC. The letter also mentions two men: the addressee, Demonassa’s husband, Anthesterius (Ἀνθεστήριος), and a certain Ankhitheos (Ἀνχ̣ίτεος = Ἀγχ̣ίθεος). The hypothesis further suggests that the monogram carved prominently in the centre of the bronze mirror – a ligature of άλφα and νι, – represents a gift inscription by one of these men. The publisher’s hypothesis that these two letters are a diphthong αί, which perhaps repeats the last syllable of the exclamation εὐαὶ (sic) contains a contradiction.
