Cinnabar

Definition and stakes

Portrait of Vitruvius Vitruvius,  Ten Books on Architecture (1914)

“ I shall now proceed to explain the nature of cinnabar. It is said that it was first found in the Cilbian country belonging to Ephesus, and both it and its properties are certainly very strange. First, before getting to the vermilion itself by methods of treat­ment, they dig out what is called the clod, an ore like iron, but rather of a reddish colour and covered with a red dust. During the digging it sheds, under the blows of the tools, tear after tear of quicksilver, which is at once gathered up by the diggers. ”

Norman Kemp Smith,  Avenarius' Philosophy of Pure Experience… (1906)

“ We preserve the simpler attitude so long as it works; when it breaks down we correct its conclusions from the more concrete standpoint. Taking into account the relation of the cinnabar to the self we observe that only when the vibrations caused by it affect the nerve-endings, and thereby the brain, do we perceive the coloured cinnabar. Though all observers apprehend the same cinnabar, each apprehends it in relation to a different self, and therefore, it may be, differently. ”

Sidney Farnsworth,  Illumination and Its Development in the Present Day

“ Cinabrese is a mixture of sinopia with chalk. Cinnabar, as mentioned before, is mercuric sulphide, which, when artificially prepared, is termed vermilion. There is hardly any doubt that the variety Cennino was familiar with was the artificial kind, for he remarks that it “is produced by alchemy, performed in an alembic.” Minium is red lead, while amatisto is probably hæmatite. Dragon’s blood, as already referred to, is a resinous colour, and lakes were prepared from various dyes.
The yellow pigments were ochre, giallorino, orpiment, risalgallo, zafferano, and arzica.
