A dissertation upon the uncertainty of the Roman history during the first five hundred years. : In two parts. Part I. A critical inquiry concerning the original records, memorials, treaties, and other monuments, from whence proper materials could be drawn for compiling the history of the first ages of Rome; and of the historians who compiled the same. Part II. An examination of some of the principal events that are said to have happen'd during that period; wherein the inconsistency of the historians with one another, and with the few original pieces that were sav'd, when Rome was burnt by the Gauls, is prov'd. Translated from the French.
