In figure 18.6, east (Ta'ir = (l Aquilae = Skt. Sravana nak~atra) is at the top, and Jah-Qutb represents the north-south axis. Each symbol appears twice on the card, at the directions of the rising and setting on the horizon of the constellation repre sented; hence the bilateral symmetry on either side of north. The cards were relatively accurate sailing guides for rhumbs close to north but increasingly inaccurate for sailing farther to the south.8 The compass card was used by providing a pair of symbols to be inscribed at either end of each of the numerous stellar rhumb lines drawn on the chart, so as to indicate sailing directions for specific legs of a voyage. Figure 18.7, adapted from Arunachalam (and correspond ing to the area represented by the right portion of fig. 18.3 and also rectangle E on fig. 18.4) illustrates the sys tem for sailing to the northeast of Kanniyakumari (Cape Comorin) at the southern tip of India and for sailing along any of the coasts of Sri Lanka.9 The lowest rhumb line on the map shows a west-east bearing and has symbols signifying those two directions. Above the eastern ter minus of that line is a rhumb, its symbols signifying a route from southwest to northeast. That it does not actually appear to go to the northeast (as it would on a European portolan chart or a Mercator projection) poses no difficulty, since it is the symbols rather than the appar ent direction of the line that matter to the map user. The next rhumb indicates, according to the symbols, a north FIG. 18.1. FOLIO OF AN INDIAN ROZ NAMA (NAUTICAL south bearing; but the line actually appears to be veering MANUAL).
