Chronicle of Abbot Ralph of Coggeshall
The Chronicle of Abbot Ralph of Coggeshall (Chronicon Anglicanum) is an indispensable medieval history that brings to life centuries of English and European affairs through the eyes of a learned Cistercian monk. Ralph of Coggeshall, abbot of the Abbey of Coggeshall in Essex in the early 13th century, continued and expanded his community’s chronicle, documenting events from the Norman Conquest of 1066 into the tumultuous reign of King Henry III. Blending eyewitness testimony, careful compilation, and the monastic commitment to record-keeping, this chronicle offers a rare narrative of political intrigue, royal power struggles, and social upheaval in England and beyond. Ralph’s work captures the reigns of pivotal figures such as Richard I and King John, providing invaluable insights into their characters, decisions, and the forces that shaped medieval rule. More than a simple annal, Chronicon Anglicanum conveys the texture of medieval life and governance, making it a rich source for scholars and readers fascinated by English history, monastic authorship, and the shaping of the medieval world.

This book is a line by line translation of the first of Meyer’s books; lines 1-10152. Book 1 of the History begins in 1139 and ends in 1194. It describes the events of the Anarchy, the role of William’s father John, John’s marriages, William’s childhood, his role as a hostage at the siege of Newbury, his injury and imprisonment in Poitou where he met Eleanor of Aquitaine and his life as a knight errant. It continues with the accusation against him of an improper relationship with Margaret, wife of Henry the Young King, his exile, and return, the death of Henry the Young King, the rebellion of Richard, the future King Richard I, war with France, the death of King Henry II, and the capture of King Richard, and the rebellion of John, the future King John. It ends with the release of King Richard and the death of John Marshal.

Effigy of John de Montacute. SIR JoHN DE MoNTACUTE, or Montagu, (Mons acutus and Mont aigu are synonymous appellatives,) was the son of [his father] William first Earl of Salisbury, to which title his elder brother William [aged 61] succeeded. He served in the wars in France under Edward the Third, and was at the battle of Crecy in 1346. In 1372 he is mentioned as in the King's fleet at sea in the retinue of his brother the Earl of Salisbury. He was present in the expedition into Scotland undertaken by Richard the Second [aged 22], A. D. 1385. He was then a Knight Banneret, and was retained to serve the King in person, attended by another banneret, five knights, and their esquires, sixty men-at-arms, and sixty archers. As Steward of the King's Household, he was sent to conduct into England Ann of Bohemia [aged 23], with whom Richard the Second had contracted marriage. He married Margaret, daughter and inheretrix of Thomas de Monthermer, in whose right he held divers lordships and manors, and was summoned to Parliament as a Baron of the Realm from the 31st of Edward III. to the 13th Richard II. 1389, in which year he died. His will was dated the 20th March, 1388, and directed that he should he buried in the cathedral church of Salisbury [Map], between two pillars, or, in case he should die in London, in the cathedral church of St. Paul, where he was baptized. He ordered that a black woollen cloth should be laid over his body, covering it and the hearse on which it rested, the ground underneath to be spread with cloth of russet and white, of which every poor man attending his funeral should have enough to make himself a coat and a hood. That on the day of his funeral the lights should consist of hve tapers, each weighing twenty pounds, four mortaries, each of ten pounds weight, and twenty-four torches, to be borne by as many poor men in russet and white. That the emblazonments about his herse should consist only of one banner of the arms of England, two of the arms of Montacutea, and two of Monthermer; by the last the hve tapers were to be placedb. That there should be a plain tomb made for him, with the image of a knight thereon, bearing the arms of Montagu, or Montacute, and having a helmet under his head. He was interred in the Lady Chapel of Salisbury Cathedral [Map], and his tomb still remaining shows that the directions of his will were pretty closely followed. Under his head is his helmet, having a griffin for crest. His surcoat quarters. Argent, three lozenges in fess Gules, for Montacute; Or, an eagle displayed Vert, for Monthermer.
Details. Plate I. 1. Ornament on the girdle. 2. Figure as originally painted. Plate II. Profile. 1. Part of the wing of the grifhn, &c. 2. Lace of the caniail, passing through loops on the basinet. 3. Gauntlet enlarged. 4. Hilt and part of the scabbard of the sword, round which is twisted the belt.
Note a. The shield of Montacute may to this day be observed on a buttress of one of the buildings in the Court of Carisbrooke Castle [Map], Isle of Wight. The gateway, and many other parts of that fortress, are evidently of the time of Richard the Second, and William Montacute, Earl of Salisbury, in the 9th of that King's reign, had a grant of the Isle of Wight, Carisbrook Castle, and the royalties on them dependent.
Note b. Of the disposition of these tapers and mortars, or mortuary lights, at funeral solemnities, an excellent idea will be acquired from the print of the funeral of Abbot Islip, published by the Society of Antiquaries, in their Vetusta Monumenta.
