Wulfstan (sometimes Wulfstan II or Lupus; died 28 May 1023) was an English Bishop of London, Bishop of Worcester, and Archbishop of York. He is thought to have begun his ecclesiastical career as a Benedictine monk. He became the Bishop of London in 996. In 1002 he was elected simultaneously to the diocese of Worcester and the archdiocese of York, holding both in plurality until 1016, when he relinquished Worcester; he remained archbishop of York until his death. It was perhaps while he was at London that he first became well known as a writer of sermons, or homilies, on the topic of Antichrist. In 1014, as archbishop, he wrote his most famous work, a homily which he titled the Sermo Lupi ad Anglos, or the Sermon of the Wolf to the English. Besides sermons Wulfstan was also instrumental in drafting law codes for both kings Æthelred the Unready and Cnut the Great of England. He is considered one of the two major writers of the late Anglo-Saxon period in England. After his death in 1023, miracles were said to have occurred at his tomb, but attempts to have him declared a saint never bore fruit. Life Wulfstan's early life is obscure, but he was certainly the uncle of one Beorhtheah, his successor at Worcester but one, and the uncle of Wulfstan of Worcester. About Wulfstan's youth we know nothing. He probably had familial ties to the Fenlands in East Anglia, and to Peterborough specifically. Although there is no direct evidence of his ever being monastic, the nature of Wulfstan's later episcopal career and his affinity with the Benedictine Reform argue that he had once studied and professed as a Benedictine monk, perhaps at Winchester. According to the Anglo-Saxon Chronicle, Wulfstan was consecrated bishop of London in 996, succeeding Aelfstan. Besides the notice in the Chronicle, the first record of his name is in a collection of nine Latin penitential letters collected by him, three of which were issued by him as bishop of London, and one by him as "Archbishop of the English". The other five letters in the collection (only one of which is addressed to Wulfstan, as archbishop) were issued by Pope Gregory V and by a Pope John (either Pope John XVII or Pope John XVIII). In the letters issued by Wulfstan as bishop of London he styles himself "Lupus episcopus", meaning "the bishop Wolf." "Lupus"
