Volumen tertium.
This is a 16th-century alchemical treatise, a volume in Latin attributed to Raymond Lull's circle and printed in Europe, likely for scholars and practitioners of alchemy. The pictures are small black-and-white woodcuts: upright stacked vessels with domed lids, a cylindrical still with a spout, and a decorative armoured-figure title border, rendered with dense hatching and clean outlines that suggest strong models for vintage scientific diagrams and ornamental frames.
