The department's research library for historical arms and armor is one of the best in the world. In addition to many important texts both well known and obscure, it also includes endless unexpected treats that warm the heart of true armor wonks. One is this copy of Gross's 1786 book, famous among armor students as the first English language book on the subject. It came to us from the library of former Met curator Stephen Grancsay (1897-1980), who got it from the library of the renowned scholar and collector, Charles Alexander the Baron de Cosson (1843-1929), the doyenne of arms and armor studies from the 1880s through the 1920s. The fun part is that the book is inscribed to de Cosson "from Papa...1866." We all got our start somewhere and often with a nudge, intentional or not, from a parent.
