Summary:
Manuscript 511 is a copy of the commentary of the Augustinian
philosopher Aegidius Romanus (ca. 1243 - 1316) on Aristotle's De
Sophisticis Elenchis (On Philosophical Refutations). In this work,
which is part of Aristotle's writings on logic - the so-called
Organon - he sets out the different types of logical fallacies.
Aegidius dedicated his commentary to Philip IV of France, whose
educator he had been; the dedication is found in most copies,
including this one. The last leaves (ff. 108r-109r) have been used
roughly contemporarily to draw up a number of tables. The first
contains the mean movement of the moon for periods of 28 years,
starting at the beginning of our calculation (the radix) and
continuing until 1512. The positions are given in signa, gradus,
minuta and secunda. The second table gives similar numbers for each
of the 28 years within such a period. The third table narrows it
further down to the individual months. The fourth table gives the
numbers for calculating the equation of the moon and the
eccentricity of its orbit. The text is written in a small hybrid
script, containing many abbreviations, in two columns per page.
Decoration is sparse: the primary textual parts (dedication,
prologue, and the questions) are preceded by a decorated initial in
penwork. The only other decoration is paragraph marks in red and
blue ink. Apart from an initial the questions are also introduced
by the first line having been written in majuscules. Annotations
and other traces of use (including expungations) are found
throughout. The codex is bound in a white leather binding, with
blind stamped covers. Traces of mounds and a clasp are visible and
the fenestra is found on the back cover. The cross-shaped stamp of
the Ten Duinen abbey is found on the first and last leaf of
Aegidius' commentary. [Summary by Dr. Mark Vermeer] Title:
