DIPLOMATICS, from the same rod as Diplomacy, is a term used to express the acquaintance with ancient documents of a public or political character, and especially of the determination of their authenticity and their age. But the ad jective, diplomatic, is usually applied to things or persons connected not with di plomatics, but with diplomacy. Thus by diplomatic proceedings we mean pro ceedings of diplomacy , and the corps di plomatique, or diplomatic body, at any court or seat of government, means the body of foreign agents engaged in diplo macy that are resident there.
Some of the most important works upon the science of diplomatics are the following :=Ioannis Mabillon de Re Diplomatica,' lib. vii., fol., Paris, 1681 1709, with the ' Supplementum,' fol., Paris, 1704 ; to which should be added the three treatises of the Jesuit, Barthol.
