ICHNOGRAPH'IA (ἰχνογραφία). A chart, map, or ground-plan, made in outline by architects and surveyors for the workmen to build by, or as a map of reference. (Vitruv. i. 2. 2.) The annexed engraving (Ichnographia/1.1) affords a specimen of Roman mapping, from a plan of the city engraved upon slabs of marble, originally forming the pavement of the temple of Romulus and Remus; many fragments of which are preserved in the Capitol. It is supposed to have been executed in the age of Septimius Severus; and when entire, afforded a complete guide to the city, in which every street, house, and public edifice was laid down in its proper place, and in sufficient detail to show its ground-plot and architectural design, together with the name of each inscribed upon it. The fragment here introduced shows the original plan of the portico of Octavia surrounding the temples of Jupiter and Juno; of all which buildings considerable remains are still standing near the present fish market. The dotted lines are only cracks in the marble. Other specimens from the same plan are presented at pp. 67. 248 and other parts of this work, some of which indicate the great skill with which the ancient draughtsmen contrived to express constructive forms by a few simple outlines.
