The Arachni Trio in Greek Mythology

i always remember this one very bizarre scene from the anneid from virgels anneid so we have in book six of the anneids famous mostly for being the book where he goes down to the underworld. There's just a bit where they come ashore on italy uh and it's this trojan he was famed according to virgels as he tells us for being the best trumpeteer out of all of the trojans. They've come ashore and they found his dead body there why has this just happened? It turns out his trumpet playing was so good that tritten became jealous of it and just snatched him off the boat and drowned him.
