Homer talks of these siren who sing such soulful songs, that enraptured the travelling sailors
Maybe maybe not.
Sometimes I wonder if the song of the siren was ethereal and enraptured because it would bring the song that was within, the secret visions and the unacknowledged fear. After all a sorceress would be able to tap them and sing them for us.
The song would make us the hero on our journey, we slay monsters, up the monsters never really die they only re-form .
The immortals, then weaken when not remembered and honoured. Our faith in them is what keeps them alive.
