This renunciation of allegiance was a declaration of open war. The chapter thus opened in the memoirs of the Leinster Geraldines closed at Tyburn on the 3rd of February, 1537. Within these three years, the policy of annexation was hastened by several events—but by none more than this unconcerted, unprepared, reckless revolt. The advice of the imprisoned Earl to his son had been "to play the gentlest part," but youth and rash counsels overcame the suggestions of age and experience. One great excess stained the cause of "Silken Thomas," while it was but six weeks old. Towards the end of July, Archbishop Allan, his father's deadly enemy, left his retreat in the Castle, and put to sea by night, hoping to escape into England. The vessel, whether by design or accident, ran ashore at Clontarf, and the neighbourhood being overrun by the insurgents, the Archbishop concealed himself at Artane. Here he was discovered, dragged from his bed, and murdered, if not in the actual presence, under the same roof with Lord Thomas. King Henry's Bishops hurled against the assassins the greater excommunication, with all its penalties; a terrific malediction, which was, perhaps, more than counterbalanced by the Papal Bull issued against Henry and Anne Boleyn on the last day of August—the knowledge of which must have reached Ireland before the end of the year. This Bull cited Henry to appear within ninety days in person, or by attorney, at Rome, to answer for his offences against the Apostolic See; failing which, he was declared excommunicated, his subjects were absolved from their allegiance, and commanded to take up arms against their former sovereign. The ninety days expired with the month of November, 1534.
