Haec pars diuiditur in duodecim partes seu loca, disposita et proportionata ad quaestiones, secundum materiae diuersitatem, ex qua sunt. Nam in uno loco siue parte est significata solutio unius quaestionis, et in alio loco solutio alterius quaestionis. Propter quod diuersimode applicabimus quaestiones ad praedicta loca. Et hoc duobus modis, uidelicet faciemus aliquas quaestiones, quas soluemus; et alias, quas non soluemus, similiter faciemus. Et istas dimittemus artistae bene intuenti, ut ipse bene abstrahat solutionem ab illa parte siue loco, cui quaestiones transmittemus; nam in illa parte siue loco solutio est significata. Hic uero paucas quaestiones faciemus et soluemus causa breuitatis. Nam haec Ars abstracta est ab Arte magna, ut ipsa breuius tractetur ut intellectus sub paucis uerbis apprehendat multa. Et sic intellectus est magis uniuersalis. Et per solutiones istarum quaestionum, sic positas seu datas, poterit dari solutio aliarum quaestionum suo modo. Loca siue partes, ad quas transmittemus quaestiones, sunt duodecim, ut iam supra dictum est, uidelicet: (1) Prima figura, (2) secunda figura, et (3) tertia figura, (4) quarta figura, (5) definitiones, (6) regulae, (7) tabula, (8) euacuatio tertiae figurae (9) multiplicatio quartae figurae, (10) mixtio principiorum et regularum, (11) nouem subiecta, (12) centum formae. Et primo de prima parte siue loco dicemus.
This part divides into twelve parts, or places. They are arranged and matched to the questions according to the diversity of the subject matter the questions arise from. For in one place, or part, the solution of one question is signified, and in another place the solution of another question. So we will apply the questions to these places in different ways. We will do this in two ways. We will raise some questions and solve them. We will likewise raise others and not solve them. Those last we will leave to the attentive artist, so that he can properly draw the solution out for himself from the part or place to which we send the questions. For in that part or place the solution is signified. Here, for the sake of brevity, we will raise only a few questions and solve them. This Art has been drawn out of the Ars magna so that it can be treated more briefly, and so that the intellect can take in many things in few words. In this way the intellect is more universal. And through the solutions of these questions, set out and given in this way, the solution of other questions can be given, each in its own way. The places, or parts, to which we send the questions are twelve, as was already said above. They are: (1) the First Figure, (2) the Second Figure, and (3) the Third Figure, (4) the Fourth Figure, (5) the definitions, (6) the rules, (7) the table, (8) the evacuation of the Third Figure, (9) the multiplication of the Fourth Figure, (10) the mixture of the principles and the rules, (11) the nine subjects, (12) the hundred forms. We will speak first of the first part, or place.
