to which a thirteenth homily The Sacrament of the Alter was added by another hand. Twelve of the thirteen homilies in Edmund Bonner's (1555; ten of these were by John Harpsfield, two by Henry Pendleton and one by Bonner himself) were translated into Cornish by John Tregear, and are now the largest single work of traditional Cornish prose. The thirteenth homily in the Cornish translation is taken from an unidentified source. Tregear was "not a skilled translator", and often used English loanwords or loan translations. According to Alan Kent, this could have been when Tregear was unable to remember the translation due to the significant decline in the knowledge and understanding of Cornish at the time, perhaps intending to return to correct them later. The Homilies were discovered in April 1949 by John Mackechnie in the papers of the Puleston family in the collection of the British Museum. Other works Nicholas Boson (1624−1708) wrote three significant texts in Cornish, Nebbaz gerriau dro tho Carnoack (A Few Words about Cornish) between 1675 and 1708; (John of Chyannor, or, The three points of wisdom), published by Edward Lhuyd in 1707, though written earlier; and The Dutchess of Cornwall's Progress, partly in English, now known only in fragments. The first two are the only known surviving Cornish prose texts from the 17th century. Boson's work is collected, along with that of his son John Boson and his cousin Thomas Boson (1635–1719) in Oliver Padel's The Cornish writings of the Boson family (1975). Late period and revival 18th century to 1950 Fragments of Cornish writing continued to appear as the language was becoming extinct during the 18th century. However, in the late 19th century a few works by non-native speakers were produced; these efforts were followed by a more substantial revival in the 20th and 21st centuries. Of the early pieces the most significant is the so-called "Cranken Rhyme" produced by John Davey of Boswednack, one of the last people with some traditional knowledge of the language. The poem, published by John Hobson Matthews in 1892, may be the last piece of traditional Cornish literature. In 1865 German language enthusiast Georg Sauerwein composed two poems in the language. Later Hobson Matthews wrote several poems, such as the patriotic "Can Wlascar Agan Mamvro" ("Patriotic Song of our Motherland"), and Robert Morton Nance, a disciple of Henry Jenner, created a body of verse, for example "Nyns
