detailed soldier-eye descriptions on the conditions and men on this campaign. He accompanied Wingfield on various diplomatic missions abroad, most notably around France, which accounts for his extensive knowledge on French culture and history. On an expedition in 1523, Gruffydd accompanies Wingfield to London, giving vivid descriptions of Thomas Wolsey in the Court of Star Chamber. Between 1524 and 1529, he was residing in London as caretaker of Wingfield Place. The nature of Gruffydd's work was never revealed. In his own Chronicle he describes duties that took him outside London: to Essex and Kent in 1525 and to Poplar in 1527. During his stay in London he observed many political figures and witnessed events at the Court of Star Chamber. It was during this time that he began penning his first extensive work Cardiff MS 5, also known as Phillipps 10823, which featured a collection of prose and poetry based loosely of the late medieval tradition. On 27 January 1529, Gruffydd travelled back to Calais, where his master Sir Robert Wingfield was serving as deputy governor. Henceforth he was known as "The soldier of Calais". Here he wrote two more works called Castell yr Iechyd, or The Fortress of Health, which was a collection of Welsh translations of medical works, and Cronicl o Wech Oesoedd, Gruffydd's immense chronicle of the world. This chronicle was written in Welsh, despite his long residence in England and France, consisting in large part of translations and adaptations of English and French sources. The fact that he includes in the work a version of Ystoria Taliesin, is highly significant for medievalists, as this is the earliest surviving copy of the legend of Taliesin's birth and acquisition of the gift of vision. Though he recorded it in the sixteenth century, Gruffydd gives evidence of earlier sources, hinting toward a ninth-century origination date. He spent the remainder of his life in Calais transcribing various manuscripts, mostly likely from the Wingfield family library. He lived as a bachelor soldier and married a Calais girl named Elizabeth Manfielde. He inherited some property through her and they had two children together. As the Protestant wave swept Europe, Gruffydd converted from Catholicism and became a convinced Protestant some time around the 1540s. Deeply influenced by Thomas Cromwell, Gruffydd was the first Welsh Protestant to leave a record of his religious views. The exact date of his death is unknown, but the
