The Dublin of Joyce's youth was a city of paradoxes, where piety and profanity, nationalism and cosmopolitanism, went hand in hand. It was a city of narrow streets and narrow minds, where the Catholic Church held sway over the lives of its citizens, and where the British Crown exercised a distant but palpable authority. Yet it was also a city of wit and humor, satire and irons where Oscar Wilde and George Bernard Shaw had honed their craft. Joyce's own family embodied these contradictions: his father, John Stanislaus Joyce, was a singer and a drinker, a devout Catholic, and a fervent nationalist who nonetheless harbored a deep love of Shakespeare and a disdain for the pretensions of the Irish middle class.
