Schmidt's book has arrived, and cryptoscopophilia proves, as expected, to be the original spelling. Schmidt also proves to be the coiner of the other words Espy selected (which were among the milder ones).
Found it: p. 304 of An Almanac of Words at Play, with the expected definition "The desire to look through the windows of homes that one passes by". (What is it about passing by?--see the definition of bovilexia).
Crytoscopophilia is indeed a misspelling of cryptoscopophilia. I think it first appeared in Willard R. Espy's An Almanac of Words at Play in 1975. I have a copy of the book, but it's not indexed. I'll see if I can root it out.
Fell in love with crytoscopophilia 15 years ago when I first encountered in Bryson's charming book. It put a name on a condition that I'd cheerfully suffered from since childhood. Here is the problem I have with this word: I can find it nowhere else. All roads lead back to Bryson, and I believe the word originated with a typo. I'm not an etymologist, but I believe the word should be cryPto- for hidden rather than cryto- for frozen. Just makes sense.
Can anyone set me straight, or has anyone else been bothered by this?
