 Although his commentary on books I and II of the Sentences is by far Gregory’s largest and most important work, historians of medieval philosophy have recently devoted some attention to his sole writing on economic thought, which was printed in Reggio Emilia in 1508 as the Tractatus de imprestantiis Venetorum et de usura and reprinted in Rimini itself over a century later in 1622 (Rimini 1508; Lambertini 2003, 2009; Kirshner 2015). The only known manuscript witness is in a codex containing various political and economic tracts: Florence, Biblioteca Nazionale Centrale, Conv. Soppr. J. X. 51, ff. 201r-212r. The manuscript carries a different redaction of the text, but it can be used to correct the printed editions and should form the basis of a future critical edition. The title and explicit in the manuscript further identify the work as a quaestio disputata on the forced loans of the Venetian commune according to the determination of Gregory of Rimini, Master of Theology and prior general of the Augustinians. Terminology in the text itself confirms that rather than a purely written work, the piece derives from an oral disputation, although the internal structure and the existence of two redactions indicate that it was much revised afterwards. Since we know that theologians’ administrative responsibilities did not preclude their participation in such events as quodlibetal disputations, it is possible that the debate took place while Gregory was his order’s prior general as the incipit says, i.e., in the latter half of 1357 or in 1358, which would make it his last word on intellectual matters.
