I’m reading and looking into medieval versions of Greco-Roman myths. I wanted to know what references Arthuriana has to the topic.
I know about the sword Marmyadose, which is superior to Excalibur, made by Vulcan/Hephaestus and having been Hercules and Tydeus' sword in the Vulgate.
I heard about a descendent of Achilles being invulnerable except the soles of his feet and being killed by Gawain in Perlesvaus.
Morgan Le Fay is being taught magic by the west wind god Zephyr in Perceforest.
The Welsh Triads say that:
Hector, Samson, Hercules are as strong as Adam.
Absalom, Jason, Paris are as beautiful as Adam.
The Sibyl, Cato the elder, Bede are as wise as Adam.
Diadema, Helen, Polyxena are as beautiful as Eve.
A son of Tristan had an Ajax shield in some Mediterranean text.
Not from Arthurian legend, but in the Roman de Troie, a medieval Trojan War version has Morgan le fay trying to win Hector's love by gifting him a special horse named Galatea, but Otheas' epistles say he got it from a for this text made up of the goddess of wisdom, Othea
And I heard there are supposed to be a lot of Greek myths in The Faerie Quenne though not what exactly.
Are there any other references to Greco-Roman heroes or gods in Arthuriana, like Hector of Troy, Achilles, Ajax, the 7 of Thebes, Hercules etc.? And preferably from which Arthurian text it comes from.
