Before he could do so, however, a yet loftier destiny was proposed to him for his favourite son. At the end of January 1185 Heraclius, the patriarch of Jerusalem, came to England to implore Henry’s aid for the perishing realm of Palestine. King Baldwin IV. was dying; after him there was but one male heir left of the blood of King Fulk of Anjou and Queen Melisenda, and that one was a little child. From the story as told by Gerald it seems plain that Heraclius aimed at something more than merely persuading Henry to take the command of a crusade; his project was nothing less than a transfer of the succession from the younger to the elder Angevin line--from the infant son of Fulk’s grand-daughter to a son of Fulk’s grandson, Henry. When the king of England, after taking counsel with his “faithful men,” declared that he could not in person undertake the deliverance of the Holy Land from its enemies, Heraclius still persisted in his other request; he implored Henry to send at least one of his sons--if even it were only John--“that from this scion of the Angevin house the seed royal might be raised up and spring into new life.” The king, however, would not listen. John, it is said, was inclined to embrace the patriarch’s suggestion, and threw himself at his father’s feet to beg his consent, but in vain.[46] At Mid-Lent Henry knighted him at Windsor, and publicly gave out that he was to proceed at once to Ireland, where he was destined to be king.[47] [Sidenote: 1175] The dominions of the English Crown in Ireland were defined by the treaty made between the Irish Ard-Righ, Roderic of Connaught, and Henry II. in October 1175 as consisting of the ancient Irish kingdoms of Meath and Leinster, the cities of Dublin and Waterford, and a tract of land extending from Waterford as far as, and including, Dungarvan.[48] Meath had been granted by Henry in 1171 to Hugh de Lacy to hold in chief of the Crown by the service of fifty knights;[49] Leinster had been granted a few weeks before to Richard de Clare, earl of Striguil.[50] The cities of Dublin and Wexford and the territory appertaining to each of them, which had been held by the Ostmen, were not included in these grants, but were reserved by Henry to himself, and placed under the charge of custodians appointed by him. His authority over the whole area occupied by his subjects in Ireland was represented by a governor whose headquarters were at Dublin, and who at the time of the treaty was Earl Richard, the lord of Leinster.[51] [Illustration: I.
