JOACHIM'S WORKS: chronology, editions, and manuscripts.

Joachim worked on his masterpieces from 1176 (which is probably the date in which his first writing appeared) to 1202, the year of his death .It is not easy to state an exact chronology of Joachim's works, since he wrote indiscriminately on the same work over a long period of time. A typical example of Joachim's method is the Psalterium Decem Cordarum, completed between 1186 and 1187, which was revised, modified, and re-revised again in 1201 as the codex Padua, Biblioteca Antoniana, ms. 322 states. Moreover, Joachim's main works, such as the Concordia and the Commentary on the Apocalypse, were written over a long period of time: the Concordia and the Expositio were begun between 1183 and 1184, but the former was completed around 1196 and the latter in 1200. At the same time, Joachim worked on other shorter treatises. Another issue concerns the commentary on the Apocalypse. The principal work, the Expositio in Apocalypsim, is in fact, accompanied by a series of introductory studies written contemporarily with the main commentary. The last example of the writer's method, Tractatus in expositionem vite et regule beati Benedicti, a collection of different sermons, was written in different periods of time. A recent reconstruction of the chronology of Joachim's works is offered by K.V. Selge. The German scholar divides Joachim's works into two sections, the first, starting in the 80's of the XII century ( which is when Joachim leaves Corazzo and settles in Sila), and then begins the second section.
