This book presents an in-depth study of the Epistles and its two summaries. Mattila argues that the Ikhwānian corpus evolved from a mainly philosophical encyclopedia of the Epistles to the largely religious treatises of its summaries. Based on philological analysis, the book's first part shows the gradual transformation of the contents of the Epistles. The second part demonstrates that the Comprehensive Epistle was not composed by the same authors but instead represents an Ismāʿīlī adaptation of the encyclopedia.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e Janne Mattila\u003cbr\u003e\u003cb\u003eISBN-10:\u003c\/b\u003e 9004690131\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9789004690134\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e Brill\u003cbr\u003e\u003cb\u003eLanguage:\u003c\/b\u003e English\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 12\/04\/2025\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 298\u003cbr\u003e\u003cb\u003eFormat:\u003c\/b\u003e Hardcover\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 1.34lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 9.25h x 6.10w x 0.75d","brand":"Janne Mattila","offers":[{"title":"Hardcover","offer_id":47965948215551,"sku":"9789004690134","price":130.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/2982\/9887\/files\/img_9040cfcb-01f5-4516-a3f2-047e2d82bd3a.jpg?v=1767285912","url":"https:\/\/www.whiterainbookhouse.com\/products\/the-formation-of-the-ikhwnian-janne-mattila-9789004690134","provider":"WR Book House","version":"1.0","type":"link"}
