Venus on the Half-Shell assumed that Vonnegut wrote the book. This problem was solved by the book being reprinted under Farmer's by-line. A common element to this novel is the origin of many of the characters' and locations' names. Farmer "put in a lot of references to literature and fictional authors... Most of the alien names in Venus were formed by transposing the letters of English or non-English words." The title and paperback cover art are a reference to an Italian Renaissance tempera painting by Sandro Botticelli, "The Birth of Venus", which depicts the birth of the goddess Venus as her rising from the
Sandro Botticelli Filippino Lippi, son of his master. In June of that year he was commissioned by the judges of commercial cases to paint two panels from a set of the Seven Virtues for their court; for some reason, only one, "Fortitude" (now in the Uffizi Gallery) was finished. Botticelli both matched his style and composition to the other panels by Piero del Pollaiuolo, and tried to outshine him "with fanciful enrichments so as to show up Piero's poverty of ornamental invention." There is often uncertainty in distinguishing between the contributions of Botticelli, the Lippis, and other pupils and imitators of Botticelli.
