Note 542 — Chapter XLII
Reading edition
As we have already seen to be the case in CUL 1693, fols. 40-51-59. In Selden supra 76, the work in four parts begins at fol. 3r, “Liber magistri Rogeri Hereford de iudiciis astronomicis. Quoniam regulas artis....” At fol. 10v, Liber de tribus generalibus iudiciis astronomie ex quibus cetera omnia defluunt, editus a magistro Rogero Hereford. In three books and a prologue, opening, “Quoniam circa tria fit omnis astronomica consideracio....” The question then arises, do fol. 14v, “Incipit liber secundus de cogitatione. Sed quum iam de intentione et cogitatione tractandum...”; and fol. 18r, “Incipit liber tercius de electione vel operatione per quod fiat electio”; have reference to the last two books of Three General Judgments or to the two middle books of the work in four parts? Apparently the former, since there is no fourth part given; at fol. 20 seems to open another treatise, Liber de motibus planetarum.
MS E Musaeo 181 has the same arrangement as Selden supra 76, fols. 10-18, but ends with the second book De cogitacione. For the first of the four parts it is fuller than Selden supra 76, fols. 3-9.
Laud. Misc. 594, fols. 136-137r, beginning mutilated, opens “illius signi et duodenarie ostendentis” and ends “secunda si vero respiciens tertia. Explicit liber de quatuor partibus iudiciorum astronomiae editus a magistro Rogero de Hereford.” But the closing words, “respiciens tertia,” are those connected with the Incipit of the Book of Three General Judgments in Dijon 1045, a good illustration of the complexities of the problem.
