We just had three in a row by Robt. Browning, and it's hard for me to resist talking about one of my favorite long poems, one by him called "Caliban Upon Setebos," subtitled "Natural Theology in the Island." Anybody read it? It's entertaining as well as interesting from the standpoint of evolution. Browning takes Caliban, a minor, humanoid character from "The Tempest" and imagines him in a monologue concerning his god, Setebos. A trick to reading the poem is to catch on that Caliban almost never uses either his own name or the pronoun "I," for fear of being discovered by Setebos. So Browning uses an apostrophe to take the place of "Caliban" or "I." Other than that, it's straightforward. I'd be happy to discuss this poem with anyone.
