CHAP. 41.—ENCAUSTIC PAINTING.
In ancient times there were but two methods of encaustic[2186] painting, in wax and on ivory,[2187] with the cestrum or pointed graver. When, however, this art came to be applied to the painting of ships of war, a third method was adopted, that of melting the wax colours and laying them on with a brush, while hot.[2188] Painting of this nature,[2189] applied to vessels, will never spoil from the action of the sun, winds, or salt water.
