ORTHOGRAPH'IA (ὀρθογραφία). A geometrical or architectural drawing, representing an elevation or a section of a building; the first of which consists in showing the external front of the edifice, with all its parts, apertures, and decorations, not in perspective, but as they would appear to the eye of a spectator placed at an infinite distance from it; the latter, in showing the whole plan of the interior as it would appear in like manner if the external wall were removed. (Vitruv. i. 2. 3.) The designs which originally accompanied the work of Vitruvius being lost, we have no example left of this style of drawing amongst the ancients; but the skill they exhibited in making out ground-plans or mapping (ichnographia) will stand surety for their excellence in this other branch of the art.
