It is very rare that a work by Poul Anderson does not appeal to me but there are two in Fantasy (New York, 1981): "Pact" and "Bullwinch's Mythology." Both are humor. It is good that Anderson's many genres include humor and some of his humorous works do appeal to me, e. g., certain passages in Midsummer Tempest.
"Bullwinch's Mythology" is a list of American gods. (Digression: a Neil Gaiman novel is called American Gods.)
According to Bullwinch, writing later:
"...scholars feel assured that the divine family numbered the usual twelve." (p. 304)

Usually, I would at least summarize information about each and might also comment whereas, this time, I cannot even bring myself to read the descriptions in full! However, every humorous piece does not work for every reader. I always skip the satirical glossary when rereading the excellent There Will Be Time.
