Museums figure briefly in both of Joyce's major works, Ulysses and Finnegans Wake. In Ulysses, the protagonist, Leopold Bloom, visits the National Museum of Ireland in his epic single-day odyssey around Dublin. His purpose for the visit is to avoid his wife's lover, whom he sees on the street, but mostly to admire the divine female forms in the statuary.
"Can see them library museum standing in the round hall, naked goddesses. Aids to digestion." (p.144)Finnegans Wake contains within its dream pages a visit to a fictional Willingdone, or Wallinstone, Museum (pp 8-10). Joseph Campbell writes in A Skeleton Key to Finnegans Wake
"His heart quopped softly. To the right. Museum. Goddesses...His eyes beating looked steadfastly at cream curves of stone" (p. 150)
This Museum should be regarded as a kind of reliquary containing various mementoes symbolizing not only the eternal brother-conflict, but also the military and diplomatic encounters, exchanges and betrayals of recorded historyAnother interpretation  is that the museum was simply the outhouse behind the dreamer's pub: "For her passkey supply to the janitrix, the mistress Kathe"
