In Joyce's unrelenting examination of the tiniest details that constitute consciousness, he stops the flow of time and defers its movement with a pacifying gesture contrary to the impatient goading of the English drama, which encloses the life of its heroes in the narrow, thrusting rush of a few crowded hours. If Shakespeare—to use his own metaphor—invested in the turning of the hourglass the exploits of many years, Joyce inverts the procedure and unfolds his hero's single day into many days upon the reader.
