I have a list of 8 treatises starting from Bernard de Rosier (1436) to Conrad Bruno (1548). I am aware of later ones like de Vera, Mothe le Vayer, Wicquefort and Callieres but would like a comprehensive list. Thanks for any help.
According to V.E. Grabar in De Legatorum Jure Tractatuum Catalogos pp 229-304 there were 153 titles on diplomacy between 1625 and 1700 of which 114 were new contributions to the literature. (Maurice Keens-Soper, Francois de Callieres and Diplomatic Theory, The Historical Jounal xvi, 3, 1973 Great Britain, 485-508)
