Who was the English Bishop of London sometimes known as Lupus who wrote the recensions collectively known as "Recensions B"?
Collectio canonum Wigorniensis 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.
Pantheon (book) The Liber universalis ("universal book") is a work of Gottfried von Viterbo (c. 1120 – c. 1196). In this work, completed in 1185, he chronicles world history from the creation of the world to the time of Heinrich VI (Henry VI). The "liber" was written around 1185 and is an extended version of the previous Memoria seculorum ("remembrance of the ages") by the same author which again builds on the Speculum regum ("mirror for kings/princes") dated to around 1185. It is subdivided into 20 „particulae” ("(small) parts"), the last of which is the so-called "Gesta Friderici"' ("Frederics achievements") first dedicated to Heinrich VI but ultimately to Pope Gregory VIII. The famous prosimetrum Pantheon builds upon the liber universalis and exists in 3 editions (1187,1188,1191). The Pantheon manuscript enjoyed a wide distribution in the late middle ages.
