Chapter 1 (Telemachus), pg 8, line 242-44: Buck Mulligan has just down from the tower parapet, leaving Stephen to brood. He looks across the water...
"Woodshadows floated silently by through the morning peace from the stairhead seaward where he gazed. Inshore and farther out the mirror of water whitened, spurned by lightshod hurrying feet..."
I'm missing the basis for the metaphor "spurned by lightshod hurrying feet". Can anyone explain it? Thanks.
