Just as Joyce modeled Mulligan on his friend Gogarty, he modeled "Haines" on Gogarty’s other guest in the tower, a well-born young Englishman named Richard Samuel Chenevix Trench (1881-1909). Gogarty met Trench during a term at Oxford in early 1904, a fact which accounts for Mulligan's referring to "the oxy chap downstairs." Haine is French for “hate.”
