 Ramus’ rhetoric textbook, the Institutiones rhetoricae, written with Talon, appeared in 1545 but with only Talon’s name on the title-page. It was a kind of companion to the Dialecticae institutiones, published two years earlier. A second edition, entitled Rhetorica, though popular and frequently reprinted in new editions, never attained the diffusion and influence of his logic textbook. During the late 1550s and the 1560s Ramus published his lectures on the various arts, including physics and metaphysics. While his textbooks were succinctly organized according to very strict principles, the lectures (Scholae) were less laconic and offered more detailed discussion. They were later collected together and published as Scholae in liberales artes in a Basel edition of 1569.
