Part 1 of E. A. Posselt's Dictionary of Weaves, a plate book of about two thousand weave drawdowns for four to nine harnesses, arranged by number of harnesses and by repeat size (warp x filling) with the repeat noted on each page. The multilingual title page and preface (English, German, French) explain the arrangement, and most of the book is full-page grids of twills, satins and other weaves. The back of the volume has an article on a thousand spindle creel, a section on textile machinery and shedding mechanisms, and advertisements for looms, reeds, yarns and other books by Posselt.
