A Carmarthenshire tradition names among those who lived for a period among the Tylwyth Teg no less a person than the translator into Welsh of Bunyan's 'Pilgrim's Progress.' He was called Iago ap Dewi, and lived in the parish of Llanllawddog, Carmarthenshire, in a cottage situated in the wood of Llangwyly. He was absent from the neighbourhood for a long period, and the universal belief among the peasantry was that Iago 'got out of bed one night to gaze on the starry sky, as he was accustomed (astrology being one of his favourite studies), and whilst thus occupied the fairies (who were accustomed to resort in a neighbouring wood), passing by, carried him away, and he dwelt with them seven years. Upon his return he was questioned by many as to where he had been, but always avoided giving them a reply.'
