A table summarising Quadripartitum II.11, on the influence of the zodiacal signs and decans on the weather, drawn up by the astronomer and physician Petrus Gaszowiec, who lectured at the University of Cracow from 1456 to his death in 1474. According to Johannes de Glogovia, Petrus Gaszowiec drew up this table in 1463 (see Note below). The source text is Egidius de Tebaldis’s translation (A.2.5).

Note The Tabula was reused by Johannes de Glogovia in his Tractatus preclarissimus in iudiciis astrorum de mutationibus aeris (1490), or Book II of his Summa astrologie, where it forms Differentia 37: ‘Differentia trigesima septima. Naturas particulares signorum et facierum comprehendens quas ponit Ptholomeus secundi Quadripartiti, capitulo XI, rectificate anno domini 1463 per venerabilem virum magistrum Petrum de Gaschowycz medicine doctorem, astrologice scientie virum doctissimum cuius anima requiescat in pace. Totum signum Arietis facit tonitrua et relanpagos — (Pisces) septentrionales facientes grandines <de natura> Saturni’ (ed. Cracow, Florianus et Wolfgangus, 1514, sig. g_ir-g_iir).

Gaschowiez medicine doctorem. Totum signum Arietis facit tonitrua et lampagos — (Pisces) meridionales facientes grandinem <de natura> Saturni.’
