John Bunyan was an English writer and Puritan preacher. His tale ‘The Pilgrim’s Progress from This World, to That Which Is to come’ was an allegory and is amongst the most important pieces of religious English literature. It tells the tale of a Christian, on his journey from this world, the “City of Destruction” to the “Celestial City”. This publication has fascinated generations of readers and its popularity is particularly important with regards to its Welsh translation – ‘Taith neu Siwrnai y Pererin’ by Trebor Lloyd Evans. This version appeared in 1678, a decade after ‘The Pilgrim’s Progress’ was first published. Its translation is significant as it gave the Welsh monoglot population a taste of Bunyan’s tale in their own language.
