In Primum Euclidis Elementorum Librum Commentarii (c. 470 AD)

Πρόκλου Διαδόχου Εἰς τὸ πρῶτον τῶν Εὐκλείδου Στοιχείων — Critical Greek text edited by Gottfried Friedlein (Leipzig: B. G. Teubner, 1873, pp. 1–436) paired with Thomas Taylor’s historical English translation (London, 1788–1789 / 1792) and GEOMETOR commentary.

Proclus’s treatise stands at the crossroads of the entire GEOMETOR classical canon: preserving Eudemus of Rhodes’s lost History of Geometry (Friedlein 64–70), formulating the epistemology of mathematical imagination (φαντασία) and projection (προβολή) engaged by Petrus Hoenen in geometor/hoenen, codifying the Six Canonical Parts of a Geometric Proposition (Friedlein 203–207), and furnishing over 150 foundational citations across Thomas Little Heath’s Euclid in geometor/euclid.
