Archaeological illustration is invaluable for shallow reliefs and small objects like stone seals, flint tools, or stone beads, and it is indispensable for cataloging pottery. In brief, shorthand fashion, a simple scale drawing can record the shape of a pot, its structure, and its decoration, both inside and outside. Look up hieroglyphs in an encyclopedia and write your name using them. Measurements taken at various points will keep the image accurate. By using graph paper to transfer the image, the scale can be changed.
