I have found two remarkable religious locii in Cyrene.
The first is the temple of Zeus-Ammon which is so critical to the mythology of Alexander the Great as the Son of God. Josephus borrows (it appears) this encounter at Siwah for his discussion of Alexander's visit to Jerusalem. It also seems that Alexander is heavily discussed in Zechariah. The temple at Siwah is already in decline at the time of Alexander's visit, and declines only further from then.
The second is the cult of Asclepius at Balagrae.
Pausanias, Description of Greece 2. 26. 1 (trans. Jones) (Greek travelogue C2nd A.D.) :
Okay, so bear with me here."At Balagrai [near Kyrene, Libya] of the Kyreneans there is an Asklepios called Iatros (Healer), who like the others came from Epidauros. From the one at Kyrene was founded the sanctuary of Asklepios at Lebene, in Krete. There is this difference between the Kyrenieans and the Epidaurians, that whereas the former sacrifice goats, it is against the custom of the Epidaurians to do so."
What if Cyrenian Jews integrated with the Asclepius cult, and then in aspiration sought to integrate a the Siwan temple as well. Where Alexander meets Yahweh rather than Zeus-Hammon?
It's outlandish, hard to fathom. And yet, imagine what form the cult of these goat-sacrificing Asclepians would take?
Their Christ would be a healer who is also the legendary Son of God and prince of peace, the uniter of the the Greek world. A parallel to Serapis. A deified Alexander-Asclepius.
Again, it's outlandish, but I couldn't construct a closer Markan Jesus out of non-Christian sources. Mark is light on the prophetic material, but that's because the prophets have already created that content. We understand that Jesus is the subject of their prophecies.
We also have Lukuas of Cyrene with the pseudonym Andreas. A Greek Andreas is the famous physician of a Ptolemy, and author of important Ptolemaic medical texts.
I am also noticing a historical consensus speculating that the critical herb of Cyrene, central to the Balagrae Asclepion, silphium, would have been traded throughout the Mediterranean primarily by Jewish merchants. Religious differences aside, the silphium trade would have giving Jews an interest in the Asclepion, and moreover, the Jewish population in Cyrene is rather ancient. Among the rare pre-Maccabean diaspora locations. This lends me to expect a looser theology among them.
Finally, some have speculated that the silphium trade network specifically would have been the avenue by which the proto-Christian (Pauline) sect would have spread throughout the diaspora. So I will go ahead and say that naming Zeus Hammon as Yahweh, treating Alexander as a subject of Jewish prophecy, and then combining Asclepius and Alexander as their version of the heavenly priest was the particular project of the Cyrenian Jews, and that their Jesus is the basis for the Markan Jesus who later inspires the gospel narrative.
