"Tall! Tall!"Whorl

It arrived today. Hooray! Finally, I've got my own copy of IGJ. Thank you, Amazon... Given that, as well as apparently being half a dozen other people, Horn is in some sense Odysseus, am I going to discover why it was/is/will be that nobody recognised him when he finally returned home to Ithaca/Lizard? I imagine that he didn't look himself any more. I know that GW has said that TBotNS was in some ways influenced by Pilgrim's Progress, but has anyone else noticed a vaguely Bunyaneque flavour to the extremely odd (and not particularly attractive) cover picture for IGJ? (Reads) "I have paper again..." Wonderful! Nigel *This is WHORL, for discussion of Gene Wolfe's Book of the Long Sun.
