The following description of the manner in which the Egyptian paintings and sculptures were executed--from the pen of Owen Jones--will be read with interest:--"The wall was first chiselled as smooth as possible, the imperfections of the stone were filled up with cement or plaster, and the whole was rubbed smooth and covered with a coloured wash; lines were then ruled perpendicularly and horizontally with red colour, forming squares all over the wall corresponding with the proportions of the figure to be drawn upon it. The subjects of the painting and of the hieroglyphics were then drawn on the wall with a red line, most probably by the priest or chief scribe, or by some inferior artist, from a document divided into similar squares; then came the chief artist, who went over every figure and hieroglyphic with a black line, and a firm and steady hand, giving expression to each curve, deviating here and confirming there the red line. The line thus traced was then followed by the sculptor. The next process was to paint the figure in the prescribed colours." Although Egyptian architecture was essentially a trabeated style,--that is to say, a style in which beams or lintels were usually employed to cover openings,--there is strong ground for the belief that the builders of that time were acquainted with the nature of the arch. Dr. Birch mentions a rudimentary arch of the time of the fifth dynasty: at Abydos there are also remains of vaulted tombs of the sixth dynasty; and in a tomb in the neighbourhood of the Pyramids there is an elementary arch of three stones surmounted by a true arch constructed in four courses. The probability is that true brick arches were built at a very early period, but in the construction of their tombs, where heavy masses of superincumbent masonry or rock had to be supported, the Egyptians seem to have been afraid to risk even the remote possibility of their arches decaying; and hence, even when they preserved the form of the arch in masonry, they constructed it with horizontal courses of stones projecting one over the other, and then cut away the lower angles. One dominating idea seems to have influenced them in the whole of their work--_esto perpetua_ was their motto; and though they have been excelled by later peoples in grace and beauty, it is a question whether they have ever been surpassed in the skill with which they adapted their means to the end which they always kept in view.
