Question: What period of usage does the Oxford English Dictionary specify for the language that the Findern Manuscript was written in?

full_context: Document 1: Bonedd Gwŷr y Gogledd: Bonedd Gwŷr y Gogledd (English: The Descent of the Men of the North ) is a brief Middle Welsh tract which claims to give the pedigrees of twenty 6th century rulers of the Hen Ogledd, the Brittonic-speaking parts of southern Scotland and northern England. It is attested in a number of manuscripts, the earliest being NLW, Peniarth MS 45, which has been dated to the late 13th century. The text may have been composed in the 12th century. The historicity of much of the information is spurious or in doubt. Although certain parts are in agreement with the earlier Harleian genealogies, the text represents a substantial revision seeking to integrate the branches of many rulers and heroes who are prominent in other traditions, such as the Rheged prince Llywarch Hen.
Document 2: England in the High Middle Ages: England in the High Middle Ages includes the history of England between the Norman Conquest in 1066 and the death of King John, considered by some to be the last of the Angevin kings of England, in 1216. A disputed succession and victory at the Battle of Hastings led to the conquest of England by William of Normandy in 1066. This linked the crown of England with possessions in France and brought a new aristocracy to the country that dominated landholding, government and the church. They brought with them the French language and maintained their rule through a system of castles and the introduction of a feudal system of landholding. By the time of William's death in 1087, England formed the largest part of an Anglo-Norman empire, ruled by nobles with landholdings across England, Normandy and Wales. William's sons disputed succession to his lands, with William II emerging as ruler of England and much of Normandy. On his death in 1100 his younger brother claimed the throne as Henry I and defeated his brother Robert to reunite England and Normandy. Henry was a ruthless yet effective king, but after the death of his only male heir in the White Ship tragedy, he persuaded his barons to recognise his daughter Matilda as heir. When Henry died in 1135 her cousin Stephen of Blois had himself proclaimed king, leading to a civil war known as The Anarchy. Eventually Stephen recognised Matilda's son Henry as his heir and when Stephen died in 1154, he succeeded as Henry II.
Document 3: Findern Manuscript: The Findern Manuscript (CUL MS Ff.1.6) is a paper codex written entirely in Middle English and compiled in the fifteenth and early sixteenth centuries by a series of gentry who were neighbors in the countryside of Derbyshire. A list of its major texts creates a “greatest hits” of fourteenth-century secular love literature; however the volume also contains around two dozen anonymous lyrics, which have been added in the blank spaces left at the bottoms of pages and the ends of quires. There are several names and scribal signatures written into the book, including the names of five women.
Document 4: High Middle Ages: The High Middle Ages or High Medieval Period was the period of European history around the 11th, 12th, and 13th centuries ( 10011300). The High Middle Ages are preceded by the Early Middle Ages and followed by the Late Middle Ages, which by convention end around 1500.
Document 5: Nowell Codex: The Nowell Codex is the second of two manuscripts found in the bound volume Cotton Vitellius A.xv, one of the four major Anglo-Saxon poetic manuscripts. It is most famous as the manuscript containing the unique copy of the epic poem "Beowulf". In addition to this, it contains first a fragment of "The Life of Saint Christopher", then the more complete texts "Wonders of the East" and "Letters of Alexander to Aristotle," and, after "Beowulf", a poetic translation of "Judith". Due to the fame of "Beowulf", the Nowell codex is also sometimes known simply as the Beowulf manuscript. The manuscript is located within the British Library with the rest of the Cotton collection.
Document 6: Gyffard partbooks: The Gyffard Partbooks (British Library Add. MSS 17802-5) (also spelled Giffard) are an important set of English Renaissance choral partbooks, containing pieces by composers such as Thomas Tallis and John Sheppard, as well as additional unnamed composers, which are not found in other sources.
Document 7: Middle English: Middle English (ME) is collectively the varieties of the English language spoken after the Norman Conquest (1066) until the late 15th century; scholarly opinion varies but the Oxford English Dictionary specifies the period of 1150 to 1500. This stage of the development of the English language roughly followed the High to the Late Middle Ages.
Document 8: History of English: English is a West Germanic language that originated from Anglo-Frisian dialects brought to Britain in the mid 5th to 7th centuries AD by Germanic invaders and settlers from what is now northwest Germany, west Denmark and the Netherlands, displacing the Celtic languages that previously predominated.
Document 9: Medieval India: Medieval India refers to the period of the Indian subcontinent's history from the 6th century to the 16th century. It is divided into two periods: The 'early medieval period' which lasted from the 6th to the 13th century and the 'late medieval period' which lasted from the 13th to the 16th century, ending with the start of the Mughal Empire in 1526. The Mughal era, from the 16th century to the 18th century, is often referred to as the early modern period, but is sometimes also included in the 'late medieval' period.
Document 10: Early Middle Japanese: Early Middle Japanese (中古日本語 , chūko nihongo ) is a stage of the Japanese language used between 794 and 1185, a time known as the Heian Period. It is the successor to Old Japanese. It is also known as Late Old Japanese, but the term "Early Middle Japanese" is preferred, as it is closer to Late Middle Japanese (after 1185) than to Old Japanese (before 794).
Document 11: Multicultural London English: Multicultural London English (abbreviated MLE) is a sociolect of English that emerged in the late 20th century. It is spoken authentically by working-class, mainly young, people in London (although there is evidence to suggest that certain features are spreading further afield). According to research conducted at Lancaster University and Queen Mary University of London, "In much of the East End of London the Cockney dialect... will have disappeared within another generation... it will be gone [from the East End] within 30 years... It has been ‘transplanted’ to... [Essex and Hertfordshire New] towns."
Document 12: Middle High German: Middle High German (abbreviated "MHG", German: "Mittelhochdeutsch" , abbr. "Mhd. ") is the term for the form of German spoken in the High Middle Ages. It is conventionally dated between 1050 and 1350, developing from Old High German and into Early New High German. High German is defined as those varieties of German which were affected by the Second Sound Shift; the Middle Low German and Middle Dutch languages spoken to the North and North West, which did not participate in this sound change, are not part of MHG.
Document 13: Exeter Book: The Exeter Book, Exeter Cathedral Library MS 3501, also known as the Codex Exoniensis, is a tenth-century book or codex which is an anthology of Anglo-Saxon poetry. It is one of the four major Anglo-Saxon literature codices, along with the Vercelli Book, Nowell Codex and the Cædmon manuscript or MS Junius 11. The book was donated to the library of Exeter Cathedral by Leofric, the first bishop of Exeter, in 1072. It is believed originally to have contained 131 leaves, of which the first 8 have been replaced with other leaves; the original first 8 pages are lost. The Exeter Book is the largest known collection of Old English literature still in existence.
Document 14: Dering Manuscript: The Dering Manuscript is the earliest extant manuscript text of any play by William Shakespeare. The manuscript combines "Part 1" and "Part 2" of "Henry IV" into a single-play redaction. Scholarly consensus indicates that the manuscript was revised in the early 17th century by Sir Edward Dering, a man known for his interest in literature and theater. Dering prepared his redaction for an amateur performance starring friends and family at Surrenden Manor, Kent, where the manuscript was discovered in 1844. This is the earliest known instance of an amateur production of Shakespeare in England. Sourced from the 1613 fifth quarto of "Part 1" and the 1600 first quarto of "Part 2", the Dering Manuscript contains many textual differences from published quarto and folio editions of the plays. Dering cut nearly 3000 lines of Shakespearian text (including significant abridgment of the character of Falstaff) and added some 50 lines of his own invention along with numerous minor interventions. The Dering Manuscript is currently a part of the collection at the Folger Shakespeare Library in Washington, DC (Folger MS V.b.34).
Document 15: Middle English literature: The term Middle English literature refers to the literature written in the form of the English language known as Middle English, from the 12th century until the 1470s. During this time the Chancery Standard, a form of London-based English became widespread and the printing press regularized the language. Between the 1470s and the middle of the following century there was a transition to early Modern English. In literary terms, the characteristics of the literary works written did not change radically until the effects of the Renaissance and Reformed Christianity became more apparent in the reign of King Henry VIII. There are three main categories of Middle English Literature: Religious, Courtly love, and Arthurian, though much of Geoffrey Chaucer's work stands outside these. Among the many religious works are those in the Katherine Group and the writings of Julian of Norwich and Richard Rolle.
