ἄξον τὴν δεῖνα – lead
ἣν δεῖνα – < genitive (dative?) name of woman’s mother (father?) >
ἧς ἔχεις τὴν οὐσίαν – “of whom you have the substance”? (hair or fingernail clippings or a garment?)
φιλοῦσάν με τὸν δεῖνα – [in order to be?] loving me
ὃν ἔτεκεν ἡ δεῖνα – who gave birth to
I’m not sure why φιλοῦσάν is a participle and not an infinitive, or even if ἄξον (from ἄγω?) could govern an infinitive like that.
It’s interesting that his mother is invoked. I assume that there must be some magical justification for that.
The first aorist ἤξα is attested quite rare early on, but in the papyri becomes the preferred form (although Atticists continued to use the second aorist ἤγαγον). Yes, the participle is interesting. Even the Koine of the NT narrative writers would use ἵνα or the infinitive to show purpose. As it stands, “proper” grammar indicates that φιλοῦσαν should modify οὐσίαν, but that would make no sense at all. Is this just bad Greek, an error which might be recognized as such even by relatively poor contemporaneous speakers, or would it be a common Koine construction, or thirdly could it be simply a traditional way of expressing it in such formula? I haven’t read sufficient of the papyri to be sure, but I suspect the first.
