[46] The facts are given by Arturo Segre, Storia del Commercio, vol. i, p. 223. For a fuller account of credit and money-lending in Florence, see Doren, Studien aus der Florentiner Wirthschaftsgeschichte, vol. i, pp. 173-209.

[53] On the Seven Deadly Sins, chap. xxiv (Works of Wyclif, ed. T. Arnold, vol. iii, p. 153): “Bot men of lawe and marchauntis and chapmen and vitelers synnen more in avarice then done pore laboreres. And this token hereof; for now ben thei pore, and now ben thei ful riche, for wronges that thei done.”

[54] E.g., Ægidius Lessinus, De Usuris, cap. ix, pt. i: “Tantum res estimatur juste, quantum ad utilitatem possidentis refertur, et tantum juste valet, quantum sine fraude vendi potest.... Omnis translatio facta libera voluntate dominorum juste fit;” Johannes Buridanus, Quæstiones super decem libros Ethicorum Aristotelis, v, 23: “Si igitur rem suam sic alienat, ipse secundum suam estimationem non damnificatur, sed lucratur; igitur non injustum patitur.” Both writers are discussed by Schreiber (op. cit., pp. 161-71 and 177-91). The theory of Buridanus appears extraordinarily modern; but he is careful to emphasize that prices should be fixed “secundum utilitatem et necessitatem totius communitatis,” not “penes necessitatem ementis vel vendentis.”

[55] St. Antonino, Summa Theologica, pars ii, tit. i, cap. viii, § 1, and cap. xvi, § iii. An account of St. Antonino’s theory of prices is given by Ilgner, Die volkswirthschaftlichen Anschauungen Antonins von Florenz, chap. iv; Jarrett, St. Antonino and Mediæval Economics; and Schreiber, op. cit., pp. 217-23. Its interest consists in the attempts to maintain the principle of the just price, while making allowance for practical necessities.
