Having read this book I can say I am very impressed. This is a comprehensive work dealing with the history and evolution of both orders. Various makers and marks of both Turkish and European madeeeer pieces. From the detailed images it is possible to establish the period of manufacture. There is an in depth study of the jewelled pieces and given the quality of the forger's handy work there is a detaled study and listings of copies of each order. This is a work that Avsar has spent several years producing and it is nothing short of a masterpiece. If you have an interest in Orders buy this book, it is worth its weight in gold and probably the finest phaleristic studies to have appeared for several years.
