Morrice

As Stephen solves the math equation for Sargent in Nestor, he sees a little dance unfolding on the paper: "Across the page the symbols moved in grave morrice." A morris is an English folk dance in which a story is enacted by the costumed dancers—hence the following reference to "mummery." Stephen imagines the interactive algebraic symbols on the paper—"letters, wearing quaint caps of squares and cubes"—as figures moving in a morris dance: "Give hands, traverse, bow to partner."
