which is probably not due to him. There is a monograph quoted by Hartwig which is interesting for the classification of the forms of sermon: modus antiquissimus, i. e. postillatio, which is purely the exegetic homily; modus modernus, the thematic style; modus antiquus, a sermon on the Biblical text; and modus subalternus, a mixture of homiletic and text sermon. Jerome Dungersheym wrote a tract De modo discendi et docendi ad populum sacra seu de modo prædicandi (1513). He treats of his subject on three points: the preacher, the sermon, the listeners. He lays stress on Scripture as the book of the preacher. Ulrich Surgant wrote a "Manuale Curatorum" (1508), in which he also recommends Scripture. His first book gives for material of preaching the usual order credenda, facienda, fugienda, timenda, appetenda and ends by saying: "Congrua materia prædicationis est Sacra Scriptura." He uses the figure of a tree in laying stress on the necessity of an organic structure. Humanist writings In the works of the two humanists, Johannes Reuchlin (Liber congestorum de arte prædicandi) and Desiderius Erasmus (Ecclesiastes seu de ratione concionandi), the return is marked to Cicero and Quintilian. A masterwork on the art of preaching is the "Rhetorica Sacra" (Lisbon, 1576) of Luis de Granada, for modern use rather old. The work shows an easy grasp of rhetoric, founded on the principles of Aristotle, Demetrius and Cicero. He treats the usual subjects of invention, arrangement, style and delivery in easy and polished Latin. Of the same class is Didacus Stella in his "Liberdemodo concionandi" (1576). Valerio, in Italy, also wrote on the art of preaching. Another landmark on preaching are the "Instructiones Pastorum" by Charles Borromeo (1538–84). At his request Valerio, Bishop of Verona, wrote a systematic treatise on homiletics entitled "Rhetorica Ecclesiastica" (1575), in which he points out the difference between profane and sacred eloquence and emphasizes the two principal objects of the preacher, to teach and to move (docere et commovere). Laurentius a Villavicentio, in his work "De formandis sacris concionibus" (1565), disapproves of transferring the ancient modes of speaking to preaching. He would treat the truths of the Gospel according to I Tim., iii, 16. He also recommended moderation in fighting heresy. The same was the view of St. Francis Borgia, whose contribution to homiletics is the small but practical work: "Libellus de ratione concionandi". Claudius Acquaviva, General of the Jesuits, wrote in 163, "Instructio
