John of Worcester. 1058. Algar, earl of Mercia, was outlawed by king Edward (age 55) for the second time, but, supported by Griffyth, king of Wales, and aided by a Norwegian fleet, which unexpectedly came to his relief, he speedily recovered his earldom by force of arms. Pope Stephen died on the third of the calends of April [30th March]. He was succeeded by Benedict, who sent the pallium to Stigand, archbishop of Canterbury. Æthelric was ordained bishop of Sussex; and abbot Siward was consecrated bishop of Rochester. Aldred, bishop of Worcester, dedicated with great ceremony to Peter, prince of the apostles, the church [Map] which he had built from the foundations in the city of Worcester, and afterwards, with the king's license, appointed Wulfstan (age 50), a monk of Worcester, ordained by him, abbot of the new foundation. Then, having resigned the bishopric of Wilton, which he held in commendam, and restored it to Heriman, before mentioned, he crossed the sea, and went through Hungary to Jerusalem; a pilgrimage which no English archbishop or bishop is known to have performed before.
Anglo-Saxon Chronicle. 1058. This year was Earl Elgar banished: but he soon came in again by force, through Griffin's assistance: and a naval armament came from Norway. It is tedious to tell how it all fell out. In this same year Bishop Aldred consecrated the minster church [Map] at Gloucester, which he himself had raised82 to the honour of God and St. Peter; and then went to Jerusalem83 with such dignity as no other man did before him, and betook himself there to God. A worthy gift he also offered to our Lord's sepulchre; which was a golden chalice of the value of five marks, of very wonderful workmanship. In the same year died Pope Stephen; and Benedict was appointed pope. He sent hither the pall to Bishop Stigand; who as archbishop consecrated Egelric a monk at Christ church, Bishop of Sussex; and Abbot Siward Bishop of Rochester.
Note 82 He built a new church from the foundation, on a larger plan. The monastery existed from the earliest times.
Note 83 Florence of Worcester says, that he went through Hungary to Jerusalem.
In 1058 Bishop Siward was consecrated Bishop of Rochester.
In 1067 Bishop Siward died.
John of Worcester. Around Sep 1067. After this, winter being near at hand, king William (age 39) returned from Normandy to England, and imposed on the English an insupportable tax. He then marched troops into Devonshire, and besieged and speedily reduced the city of Exeter, Devon [Map], which the citizens and some English thanes held against him. But the countess Githa, mother of Harold, king of England, and sister [Note. Aunt] of Sweyn (age 48), king of Denmark, escaped from the city, with many others, and retired to Flanders; and the citizens submitted to the king, and paid him fealty. Siward, nineteenth bishop of Rochester, died.
