[Illustration: Brunetto Latini. “Li livres dou Trésor.” Page taken from the 15th century Ms. in the Bibliothèque Nationale, Paris.] =A.D. 1260.=--Brunetto Latini, _b._ 1230, _d._ 1294, “maestro del divino poeta Dante,” celebrated Florentine encyclopædist, composes his “Tesoro,” rewritten in French (“Livres dou Trésor”), wherein he speaks clearly of the compass as at some time likely to be useful at sea. But he adds: “No master mariner dares to use it, lest he should fall under the supposition of being a magician; nor would even the sailors venture themselves out to sea under his command if he took with him an instrument which carries so great an appearance of being constructed under the influence of some infernal spirit.” The “Tesoro” is said to be a kind of abridgment of the Bible, of Pliny, of Solinus, of the Ethics of Aristotle, of the rhetorical writings of Cicero and of the political works of Aristotle, Plato and Xenophon (“New Biog. Dict.,” London, 1850, Vol. IX. p. 205). It would be well to consult “La Table Générale des bulletins ... Sociétés Savantes,” par M. Octave Teissier, Paris, 1873, p. 44, regarding the collection of different manuscripts of Brunetto’s extensive work.
