But I will not omit to remark, that Cennini makes no mention of certain earths, such as the dark terra rossa, nor of cinnabar and various greens—perhaps because they were not then in use; other colours were in like manner wanting to the painters of that age, as umber for example, yellow-lake (giallo santo), the smalts, both for oil and fresco painting, with certain yellows and greens, all which have been discovered at a later period.
