Question: Who was the English Bishop of London sometimes known as Lupus who wrote the recensions collectively known as "Recensions B"?
Context: Wulfstan (sometimes Lupus; died 28 May 1023) was an English Bishop of London, Bishop of Worcester, and Archbishop of York.  He should not be confused with Wulfstan I, Archbishop of York, or Wulfstan, Bishop of Worcester.  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". Ælfheah the Bald is the commonly used name for Ælfheah (died 12 March 951), the first English Bishop of Winchester of that name.  He is sometimes known as Alphege, an older translation of his Old English name. The Collectio canonum Wigorniensis (also known as the "Excerptiones Ecgberhti" or as "Wulfstan's canon law collection") is a medieval canon law collection originating in southern England around the year 1005.  It exists in multiple recensions, the earliest of which — "Recension A" — consists of just over 100 canons drawn from a variety of sources, most predominantly the ninth-century Frankish collection of penitential and canon law known as the "Collectio canonum quadripartita".  The author of Recension A is currently unknown.  Other recensions also exist, slightly later in date than the first.  These later recensions are extensions and augmentations of Recension A, and are known collectively as "Recension B".  These later recensions all bear the unmistakable mark of having been created by Wulfstan, bishop of Worcester and archbishop of York, possibly sometime around the year 1008, though some of them may have been compiled as late as 1023, the year of Wulfstan's death.  The collection treats a range of ecclesiastical and lay subjects, such as clerical discipline, church administration, lay and clerical penance, public and private penance, as well as a variety of spiritual, doctrinal and catechistic matters.  Several "canons" in the collection verge on the character of sermons or expository texts rather than church canons in the traditional sense; but nearly every element in the collection is prescriptive in nature, and concerns the proper ordering of society in a Christian polity. Lord Arthur Charles Hervey (20 August 1808 – 9 June 1894) was an English bishop who served as Bishop of Bath and Wells from 1869 to 1894.  He was usually known by his aristocratic courtesy title, "Lord", rather than the style appropriate to a bishop, the Right Reverend. Robert or sometimes Robert of Lewes (died 1166) was a medieval English Bishop of Bath.  He began his career as a monk at Lewes Priory as well as performing administrative functions for Henry of Blois.  It was Henry who secured Robert's selection as bishop.  While bishop, Robert built in his diocese and set up the system of archdeacons there.  He may have been the author of the "Gesta Stephani", a work detailing the history of King Stephen's life. Zachary Pearce, sometimes known as Zachariah (8 September 1690 – 29 June 1774), was an English Bishop of Bangor and Bishop of Rochester.  He was a controversialist and a notable early critical writer defending John Milton, attacking Richard Bentley's 1732 edition of "Paradise Lost" the following year. Nicholas Ridley (  1500 –16 October 1555) was an English Bishop of London (the only bishop called "Bishop of London and Westminster").  Ridley was burned at the stake as one of the Oxford Martyrs during the Marian Persecutions for his teachings and his support of Lady Jane Grey.  He is remembered with a commemoration in the calendar of saints in some parts of the Anglican Communion on 16 October. Robert Burnell (sometimes spelled Robert Burnel; c. 1239 – 25 October 1292) was an English bishop who served as Lord Chancellor of England from 1274 to 1292.  A native of Shropshire, he served as a minor royal official before entering into the service of Prince Edward, the future King Edward I of England.  When Edward went on the Eighth Crusade in 1270, Burnell stayed in England to secure the prince's interests.  He served as regent after the death of King Henry III of England while Edward was still on crusade.  He was twice elected Archbishop of Canterbury, but his personal life—which included a long-term mistress who was rumoured to have borne him four sons—prevented his confirmation by the papacy.  In 1275 Burnell was elected Bishop of Bath and Wells, after Edward had appointed him Lord Chancellor in 1274. Robert de Chesney (died December 1166) was a medieval English Bishop of Lincoln.  He was the brother of an important royal official, William de Chesney, and the uncle of Gilbert Foliot, successively Bishop of Hereford and Bishop of London.  Educated at Oxford or Paris, Chesney was Archdeacon of Leicester before his election as bishop in December 1148. "Sonic X" is an anime series based on the "Sonic the Hedgehog" video game series.  It originally ran consecutively on Sundays from April 6, 2003 to March 28, 2004 with a total of 52 episodes (collectively known as the Japanese "Series 1").  Episodes 53-78 (collectively known as "Series 2") never were aired on TV or released on DVD in Japan but were available through rental streaming services (episodes 53-78 were first broadcast on TV in some other countries before they aired on UK/US television).  For the English dub produced by 4Kids (which aired on FOX on the Saturday morning block FoxBox, later renamed 4Kids TV, from 2003 to 2006), episodes 1-52 were referred to as Seasons 1 and 2, each 26 episodes long, and episodes 53-78 were referred to as Season 3; but the Saga Set DVD releases split the episodes into six seasons, each containing 13 episodes.  The airdates for TV Tokyo are listed on the left, while the airdates for the 4Kids English dub are on the right.
