Between 1180 and 1194 he was often at Court and employed in the king's affairs. Henry II. selected him as a suitable person to accompany the young prince John to Ireland in 1185, and the result was his two great works--"The Topography," and "The Conquest of Ireland," which are the chief and almost the only authorities for Irish history in the Middle Ages. The former work he read publicly at Oxford on his return; it was a great occasion: we must tell it in his own words. "When the work was finished, not wishing to hide his candle under a bushel, but wishing to place it in a candlestick, so that it might give light, he resolved to read it before a vast audience at Oxford, where scholars in England chiefly flourished and excelled in scholarship. And as there were three divisions in the work, and each division occupied a day, the readings lasted three successive days. On the first day, he received and entertained at his lodgings all the poor people of the town; on the second, all the doctors of the different faculties and their best students; and on the third, the rest of the students and the chief men of the town. It was a costly and noble act; and neither present nor past time can furnish any record of such a solemnity having ever taken place in England."
In 1188 he accompanied the Archbishop of Canterbury in his tour through Wales to preach the Third Crusade. With this we shall deal later.
He was abroad with Henry II. at the time of the old king's death, and has left a valuable account of his later years in the book "On the Instruction of Princes." His connection with the Court gave him opportunities for studying the great characters of the time at close quarters, and we have from his pen graphic sketches of many of them. Take this description of Henry II.: "He had a reddish complexion, rather dark, and a large round head. His eyes were gray, bloodshot, and flashed in anger. He had a fiery face; his voice was shaky; he had a deep chest, and long muscular arms, his great round head hanging somewhat forward. He had an enormous belly--though not from gross feeding. Indeed he was temperate in all things, for a prince. To keep down his corpulency, he took immoderate exercise. Even in times of peace he took no rest--hunting furiously all day, and on his return home in the evening seldom sitting down either before or after supper; for in spite of his own fatigue, he would weary out the Court by being constantly on his legs."
