 Other ancient sources were also important, even when they were subject to less discussion or criticism. The theory of the humors and animal spirits of the Hippocratic and Galenist medical traditions offered much of the basic vocabulary for early modern discussions of the physiology of the emotions. Rhetorical works, such as those by Aristotle and Cicero, provided a great deal of material for taxonomizing and manipulating the emotions. (Indeed, some of the distinctive early modern practice of generating long lists of emotions, as well as many of the forms of classification, can be traced to these sources.) Popular treatises, such as those by Juan Luis Vives, received a number of mentions. Less obvious, but still influential were the discussions of particular emotions in Renaissance works, such as the treatment of love and melancholy by the Florentine humanists, or that of “glory” [gloria] by Machiavelli and Montaigne. These sources overlap in ways that are not always consistent and can be difficult to trace: for instance, we find Spinoza probably paraphrasing a passage from Montaigne (E III Def of the Affects XLIV), where Montaigne criticizes Cicero’s ambitions for “glory” by directly quoting the Latin author (Montaigne, 1958, 187) – all without anything like citation of sources.
