This article contains an implicit comparison of the institutions and thought of the Italian city republics in the period from about 1150 to 1350 with medieval and early-modern monarchies and oligarchical republics, the latter being exemplified here by a passage from Bartolo of Sassoferrato. The grammarians, notaries, and jurists treated here are representative of the secular or lay professionalism that first emerged on a large scale in these republics. To these have been added occasional clerks who show the influence of (...) these legal and secular traditions, including Ptolemy of Lucca , whose On Princely Government continued a work by the far more famous Dominican Thomas Aquinas and hence enjoyed wide circulation and great influence. His work shows evidence of the influence of the translation of Aristotle's Politics done c. 1260; the only other author treated here who absorbed part of that tradition is the civilian jurist Bartolo of Sassoferrato. Most of the lawyers and other professionals derived their ideas from Roman law and, to a lesser extent, from Seneca and even Cicero. Readers may be surprised to observe that Marsiglio of Padua, surely Italy's premier political thinker, is not seen here at all or, rather, only once mentioned in passing. A reason for this is that he is much discussed in today's scholarly literature of political theory. A main intention of this author, however, has to do with him. It is to help explain the world he came from. If exaggerated, A. J. Carlyle's observation remains sound. Marsiglio, he said, “is not … setting out some new and revolutionary democratic doctrine, but is rather expressing, even if in rather drastic and unqualified terms, the normal judgement and practice of the [Italian] Middle Ages.
