Stately, plump Buck Mulligan came from the stairhead, bearing a bowl of lather on which a mirror and a razor lay crossed. A yellow dressinggown, ungirdled, was sustained gently behind him by the mild morning air. He held the bowl aloft and intoned:The design of the Modern Library Ulysses (1934), with the first letters of the novel's three sections -- S, M, P -- filling whole pages, helped to elicit some wonderful if perhaps tenuous speculations about Joyce's art. S, M, P -- subject, middle, and predicate, the three parts of a syllogism. The letters have also been understood in terms of the novel's principal figures: S for Stephen Dedalus, the focus of Stephen Dedalus' section of the novel; M for Molly Bloom, to whom Leopold Bloom's thoughts always return; P for "Poldy," Molly's Leopold, to whom she said "yes I will Yes."
—Introibo ad altare Dei.
Halted, he peered down the dark winding stairs and called up coarsely:
—Come up, Kinch. Come up, you fearful jesuit.
It may be no more than coincidence that the novel's first and last words reverse one another (s to y, y to s).
