Yes, 33 does ring a bell, but alas Frodo does not take up his burden at thirty, and dawdles a bit before heading down that road, a bit of a reluctant savior in contrast. Perhaps Tolkien only wants to hint at that reflection of True Myth. Frodo is a hobbit and not a god, after all. But the idea of him returning to the Shire for a time, and then sailing west strikes me as a wonderful parallel, as is the change in his friends upon returning to the Shire.
But it seems, I'm having trouble sticking to the first chapter here. Many apologies!
