syntaxis of Ptolemy, "the edition having been prepared
[paranagnostheisa] by the philosopher, my daughter Hypatia."

### Classroom Discussion (based on Knorr's Textual Studies...)

Discussed Rome's attempt at finding stylistic variations between
Books I thru IV. (results were not conclusive).
Discussed Knorr's theory that Rome did not find conclusive
stylistic variations because the
literal translation of [paranagnostheisa] is "reading along" instead of
"prepared". He found the same term used for Eutocius' commentary on
Archimedes, and compared this to a second Archimedes version.
Eutocius had aded new paragraphs, and
modified others, but the text was mostly
unaltered. So, Knorr looked for sections of Book III distinct
from the rest of the commentary and from the other Books.

We examined p. 802-804, parts of Books I and III (in Greek)
and p. 780-786 (English translation).

Specifically, we analyzed the mathematics in the bottom
of p. 780 and some of p. 781.
