Splendor Solis, one of the most heavily illustrated alchemical manuscripts to survive, pairs its written instructions with detailed painted scenes of vessels, furnaces and the substances working within them, giving historians a rare documented picture of how a specific apparatus was actually imagined to look and function at the time the manuscript was made.
That pictorial record matters for an alchemical apparatus entry because a manuscript's images of a vessel or furnace are themselves a documented historical source, distinct from and worth recording alongside a later technical description, since surviving illustrations sometimes preserve a documented apparatus design no written account describes in comparable physical detail.
An alchemical apparatus entry therefore records where a documented illustrated source exists for a given piece of equipment, noting what its imagery actually shows about the apparatus's construction and use, since Splendor Solis's own surviving pages demonstrate that an alchemical manuscript's pictures are working technical evidence and not only ornamental illustration. Where an apparatus appears differently across surviving illustrated sources, an entry records that documented variation rather than treating one image as definitive.
