A rigid satchel of heavy waxed leather, shaped and stitched over a stiffened inner frame to hold a travelling book flat and square. A broad shoulder strap crosses the body, buckled to sit the case at the hip where the wearer’s off-hand can steady it. A flap closes over the top, overlapping the front seam and held by a pair of brass buckles or a turnkey latch; beneath it, a smaller gusseted storm-flap folds inward to keep rain from running along the spine.
The case’s main compartment is sized for a standard travelling book; a narrower sleeve along the back holds a scribe’s kit—quills, a small knife, inkwells, blotting sand, sealing wax, a signet—and two short loops inside the flap secure a few candles for use after dark. All seams are doubled, rolled, and waxed, and the outer leather is treated against mildew, so the case sheds a hard rain and survives a fall from a packhorse without losing its shape. Scribes, itinerant sages, physicians on circuit, and mercantylers traveling the fairs favor them; clerks of the Panepistemium and temple scribes use them when sent to copy or inspect records abroad.
