Context paragraphs:
Excarpsus Cummeani: The Excarpsus Cummeani, also called the Pseudo-Cummeani, is an eighth-century penitential, probably written in the north of the Frankish Empire in Corbie Abbey.  Twenty-six copies of the manuscript survive; six of those were copied before 800 CE.  It is possible that the penitential, which extends its scope beyond monasticism to include clerics and lay people, has a connection to Saint Boniface and his efforts to reform the Frankish church in the first half of the eighth century.  Geographic spread by the end of the eighth century and continued copying of the manuscript into the 9th and 10th centuries have been interpreted to mean the work was considered "by the Christian authorities" a canonical text.  It was used as late as the eleventh century, "as the main source of the "P. Parisiense compositum".

Annales laureshamenses: The Annales laureshamenses or Annals of Lorsch (AL) are a set of "Reichsannalen" (annals of the Frankish empire) that cover the years from 703 to 803, with a brief prologue.  The annals begin where the "Chronica minora" of the Anglo-Saxon historian Bede leaves off—in the fifth year of the Emperor Tiberios III—and may have originally been composed as a continuation of Bede.  The annals for the years up to 785 were written at the Abbey of Lorsch (whence the name), but are dependent on earlier sources.  Those for the years from 785 onward form an independent source and provide especially important coverage of the imperial coronation of Charlemagne in 800.  The "Annales laureshamenses" have been translated into English.

Ferdinand van Apshoven the Younger: Ferdinand van Apshoven, 'the younger,' son of the painter of the same name, and brother of the more celebrated Thomas, was baptized in 1630.  He was a pupil of Teniers the younger, and in 1657-58 he was admitted to the Antwerp Guild as a master's son.  In 1664 he took the oath as Captain in the 13th Division of the 'Civic guard.'  In 1678-79 he was offered, but declined to accept, the office of Dean to the Guild.  In 1694 he died, and was buried in the church of St. Walburg, in Antwerp.  Ferdinand van Apshoven's pictures, like those of his brother, closely resemble the style of Teniers, under whose name many of them have passed.  An Interior, with two figures — almost equal to a Teniers — is in the Rotterdam Museum; another Chamber, with three figures, is in the Museum at Dunkirk; and a third, 'Peasants in a Tavern,' is in the possession of M. van Lerius, of Antwerp.

Faremoutiers Abbey: Faremoutiers Abbey (French: "Abbaye Notre-Dame de Faremoutiers" ) was an important Merovingian Benedictine nunnery (re-established in the 20th century) in the present Seine-et-Oise department of France.  It formed an important link between the Merovingian Frankish Empire and the southern Anglo-Saxon kingdoms of Kent and East Anglia.

Donar's Oak: Jove's Oak ("interpretatio romana" for Donar's Oak and therefore sometimes referred to as Thor's Oak) was a sacred tree of the Germanic pagans located in an unclear location around what is now the region of Hesse, Germany.  According to the 8th century "Vita Bonifatii auctore Willibaldi", the Anglo-Saxon missionary Saint Boniface and his retinue cut down the tree earlier the same century.  Wood from the oak was then reportedly used to build a church at the site dedicated to Saint Peter.  Sacred trees and sacred groves were widely venerated by the Germanic peoples.

Saint Arbogast: Saint Arbogast (or Saint Arbogast of Strassburg; German: "Arbogast von Straßburg" ; French: "Arbogast de Strasbourg" ; Latin: "Arbogastus" ; c. 600s 700 AD) was a 7th-century missionary to the Frankish Empire and an early Bishop of Strasbourg.

Saint Boniface: Saint Boniface (Latin: "Bonifatius" ; 675 – 5 June 754 AD), born Winfrid, Wynfrith, or Wynfryth in the kingdom of Wessex in Anglo-Saxon England, was a leading figure in the Anglo-Saxon mission to the Germanic parts of the Frankish Empire during the 8th century.  He established the first organized Christianity in many parts of Germania.  He is the patron saint of Germania, the first archbishop of Mainz and the "Apostle of the Germans".  He was killed in Frisia in 754, along with 52 others.  His remains were returned to Fulda, where they rest in a sarcophagus which became a site of pilgrimage.  Facts about Boniface's life and death as well as his work became widely known, since there is a wealth of material available—a number of "vitae", especially the near-contemporary "Vita Bonifatii auctore Willibaldi", and legal documents, possibly some sermons, and above all his correspondence.

Anglo-Saxon mission: Anglo-Saxon missionaries were instrumental in the spread of Christianity in the Frankish Empire during the 8th century, continuing the work of Hiberno-Scottish missionaries which had been spreading Celtic Christianity across the Frankish Empire as well as in Scotland and Anglo-Saxon England itself during the 6th century (see Anglo-Saxon Christianity).

Saxons: The Saxons (Latin: "Saxones" , Old English: "Seaxe" , Old Saxon: "Sahson" , Low German: "Sassen" , German: "Sachsen" , Dutch: "Saksen" , Welsh: "Saeson" ) were a group of Germanic tribes first mentioned as living near the North Sea coast of what is now Germany (Old Saxony), in the late Roman empire.  They were soon mentioned as raiding and settling in many North Sea areas, as well as pushing south inland towards the Franks.  Significant numbers settled in large parts of Great Britain in the early Middle Ages and formed part of the merged group of Anglo-Saxons who eventually organised the first united Kingdom of England.  Many Saxons however remained in Germania (Old Saxony c. 531-804), where they resisted the expanding Frankish Empire through the leadership of the semi-legendary Saxon hero, Widukind.  Initially, Saxons of Britain and those of Old Saxony (Northern Germany) were both referred to as 'Saxons' in an indiscriminate manner.  The term Anglo-Saxon, in turn, came into practice in the 8th century (probably by Paul the Deacon) to distinguish English Saxons from continental Saxons (Ealdseaxe, 'old Saxons').

Saint Walpurga: Saint Walpurga or Walburga (Old English: "Wealdburg" , Latin: "Valpurga, Walpurga, Walpurgis" ; c. AD 710 – 25 February 777 or 779), also spelled Valderburg or Guibor, was an Anglo-Saxon missionary to the Frankish Empire.  She was canonized on 1 May ca. 870 by Pope Adrian II.  Walpurgis Night (or "Walpurgisnacht") is the name for the eve of her day, which coincides with May Day.
