Utopia (Libellus vere aureus, nec minus salutaris quam festivus, de optimo rei publicae statu deque nova insula Utopia,[1] "A little, true book, both beneficial and enjoyable, about how things should be in the new island Utopia") is a work of fiction and socio-political satire by Thomas More (1478–1535), written in Latin and published in 1516. The book is a frame narrative primarily depicting a fictional island society and its religious, social, and political customs. Many aspects of More's description of Utopia are reminiscent of life in monasteries.[2]
St. Augustine's famous De Civitate Dei (City of God, 413–26) is frequently cited as a source for Utopia. It was, of course, well known to More. He had delivered a series of lectures on the work, as has been mentioned. The basic plan of Augustine's book is different from the Republic, although Augustine was a devoted admirer of Plato. By the same token, More's work differs in basic concept from Augustine's, though inevitably echoes of Augustine are to be found in More.

The name Raphael, though, may have been chosen by More to remind his readers of the archangel Raphael who is mentioned in the Book of Tobit (3:17; 5:4, 16; 6:11, 14, 16, 18; also in chs. 7, 8, 9, 11, 12). In that book the angel guides Tobias and later cures his father of his blindness. While Hythlodaeus may suggest his words are not to be trusted, Raphael meaning (in Hebrew) "God has healed" suggests that Raphael may be opening the eyes of the reader to what is true. The suggestion that More may have agreed with the views of Raphael is given weight by the way he dressed; with "his cloak... hanging carelessly about him"; a style which Roger Ascham reports that More himself was wont to adopt. Furthermore, more recent criticism has questioned the reliability of both Gile's annotations and the character of "More" in the text itself. Claims that the book only subverts Utopia and Hythlodaeus are possibly oversimplistic.
