Boston Public Library (Rare Books Department) copy quarterbound in early, mottled sheepskin over bevelled wooden boards. The spine contains an early leather label with the title inscribed. Brass shell clasps are present, along with the remnant of an early sheepskin thong. Bound-in at front is a medieval parchment manuscript leaf with Latin writing on both sides, the verso of which is dated 10 June [?], 1376. This leaf appears to be an original or early front pastedown. The title page contains two early ex-libris inscriptions, both of which are illegible, though one is dated 1550. At the head of the same page are the Roman numerals N XXCCCIII, under which the name Euclidus is inscribed in iron gall ink. In this copy, there is an imposition error affecting sheets n3.6 and n4.5. Most quires contain parchment guards/sewing strips. Leaves a1 and r8 are wanting.
