Raymundi Lullii opera ea quæ ad adinventam ab ipso artem universalem, scientiarum artiumque omnium brevi compendio, firmaque memoria apprehendendarum, locupletissimaque vel oratione ex tempore pertractandarum, pertinent. Ut et in eandem quorundam interpretum scripti commentarii: quæ omnia sequens indicabit pagina: & hoc demum tempore conjunctim emendatiora locupletioraque non nihil edita sunt. Accessit huic editioni Valerii de Valeriis patricii veneti Aureum in artem Lulli generalem opus: adjuncto indice cum capitum, tùm rerum ac verborum locupletißimo
Raymond Lull's Ars generalis, a 1617 Latin collection of his works on his universal art of memory and reasoning, printed at Strasbourg by the heirs of Lazarus Zetzner for scholars and students. The pictures are plain line diagrams of concentric wheels with letters and Latin labels around the rims, with one wheel showing a hub and sectors of text, offering a designer a model for schematic, mechanical-looking charts.
