A Tribute Anthology for L. Sprague de Camp edited by Harry Turtledove and published by Baen Books in 2005. Publication The original publication of the first three Pratt and De Camp collaborations ("Roaring Trumpet", "Mathematics of Magic", and The Castle of Iron) was in Unknown Magazine during its brief run. The remaining two appeared in Beyond Fantasy Magazine and Fantasy Magazine a few years later. Sir Harold and the Gnome King first appeared in the World Fantasy Convention program book in 1990 and as a chapbook the following year. It was later revised and appeared with the remainder of the later continuations in regular trade books. Yngvi In the original story a character in a jail comes to the bars every hour on the hour to announce that "Yngvi is a louse!". This phrase has moved into the lexicon and has taken on a life of its own in certain SF-related circles. Who, or what, Yngvi may be is not mentioned in the book, though in Old Norse, Yngvi is another name for the god Freyr. Bibliography Original stories "The Roaring Trumpet" (May 1940, by L.
