Abstract: According to the testimony provided in Pseudo-Apuleius’ Peri Hermeneias (XIII, p. 213.5–10 Moreschini), Aristo of Alexandria (fl. 1st century BCE) was the first Peripatetic philosopher to introduce the five subaltern modes of syllogisms in the first and second figures (Barbari, Celaront, Celantop, Cesaro, Camestrop). In the available collections of testimonia, this text from the Peri Hermeneias has been regarded as the sole source for reconstructing Aristo’s position. However, a passage in Galen’s Institutio logica (XI 3–4 Kalbfleisch) appears to reference the five new syllogistic modes developed by Aristo on the basis of Aristotle’s Prior Analytics I 4. In this paper, I aim to show, through a comparative analysis with Pseudo-Apuleius’ testimony, that Galen’s Inst. log. XI 3–4 refers to the five modes elaborated by Aristo. If the examination of the extant evidence has been conducted accurately, Galen’s passage may thus be properly recognized as a new testimony to the syllogistic system of Aristo of Alexandria. To achieve this objective, (1) I will first reconstruct the method by which Aristo deduced the five new syllogistic modes, drawing on Ps.-Ap., De Int. XIII, p. 213.5–10 Moreschini; (2) secondly, I will propose a new reconstruction of the Greek text of Galen’s Inst. log. XI 3–4, which contains numerous lacunae and interpretive challenges.
