Excavators at the site of a major Roman temple in London have found a sealed box containing a white cream still bearing the fingermarks of the person who last used it, nearly 2,000 years ago. Museum conservator Liz Barham who opened the fist-sized cylindrical tin box for the first time on Monday, in front of the world's media, described the smell from the half-full container as "sulphurous" and "cheesy." The substance, which will now be chemically analyzed, could be face cream or even face paintsaid Museum of London curator Francis Grew.

William Smith, D.C.L., LL.D., in an article in
A Dictionary of Greek and Roman Antiquities of 1875 explains, "The practice of painting the face was very general among the Greek ladies, and probably came into fashion in consequence of their sedentary mode of life, which robbed their complexions of their natural freshness, and induced them to have recourse to artificial means for restoring the red and white of nature. This at the least is the reason given by some of the ancient writers themselves (Xen. Oecon. 10 c.10; Phintys, ap. Stobaeum, tit. lxxiv.61). The practice, however, was of great antiquity among the Greeks, and was probably first introduced among the Asiatic Ionians from the East, where the custom has prevailed from the earliest times. "
He continues, "In order to produce a fair complexion, cerussa, or white lead was employed. The eye-brows and eye-lids were stained black with a sulphuret of antimony, which is still employed by the Turkish ladies for the same purpose. The eye-brows were likewise stained with a preparation of soot.
Roman ladies even went so far as to paint with blue the veins on the temples, as we may infer from Propertius (ii.14.27) "si caeruleo quaedam sua tempore fuco tinxerit." The ridiculous use of patches (splenia), which were common among the English ladies in the reign of Queen Anne and the first Georges, was not unknown to the Roman ladies (Mart. ii.29.9, x.22; Plin. Ep. vi.2). The more effeminate of the male sex at Rome also employed paint. Cicero speaks (in Pison. 11) of the cerussatae buccae of his enemy, the consul Piso.

"From Homer's day forward, precious oils, perfumes, cosmetic powders, eye shadows, skin glosses and paints, beauty unguents, and even hair dyes seem to have been in near universal use. Export and sale of these items formed an important part of trade around the Mediterranean. During the 8th and 7th centuries BC, overseas markets were dominated by Corinthian, Rhodian and East Greek perfume flasks and cosmetic containers, including aryballoi, alabastra, pyxides and other small specialized shapes. Cosmetic unguents were imported into Greece in containers carved from the Red Sea Tridacna shell."
