The scene
A manuscript sheet in brown ink and pencil on aged paper, elements set in columns with corrections and the question marks where new ones were predicted. It looks like the working page, not the tidy version.
The style
A Renaissance notebook page: brown ink on stained, foxed paper, with corrections, margin sketches and an ink blot, like a page from an inventor's notebook.
The inspiration
Dmitri Mendeleev's first periodic table (1869), in the public domain. This is a new drawing in the manner of that manuscript, not a copy of it.
How it's made
A print of a digital artwork in the style of a nineteenth-century manuscript sheet, not an original. Each carries my printed Chapter & Scene signature.
