[1889] Ceruse, white lead, or carbonate of lead, is prepared in much the same manner at the present day. Ajasson is of opinion that the native pigment discovered on the lands of Theodotus, was native carbonate of lead, the crystals of which are found accompanied by quartz.
[1890] “Burnt” ceruse. This was, in fact, one of the varieties of “minium,” red oxide of lead, our red lead. Vitruvius and Dioscorides call it “sandaraca,” differing somewhat from that of Pliny.

[1892] See B. xxxiii. cc. [56], [57].
[1893] It was possibly owing to this that the colour known as “umber” received its name, and not from Ombria, in Italy. Ajasson says that shadows cannot be successfully made without the use of transparent colours, and that red and the several browns are remarkably transparent.

[1897] See B. vi. c. 34, and B. xxxvii. c. [32].
[1898] In B. xxxiv. c. [55]. “Pliny speaks of different shades of sandaraca, the pale, or massicot, (yellow oxide of lead), and a mixture of the pale with minium. It also signified Realgar, or red sulphuret of arsenic.”—Wornum, in Smith’s Dict. Antiq. Art. Colores.
