In this Map equal distances from the centre represent equal distances on the sky from the point overhead. The double loop over the southern meridian passes through the clock-noon positions of the sun, and shows how much he is to the east of the meridian in January, February, March, &c. (and therefore after the clock), and how much he is to the west of the meridian (and therefore before the clock), in September, October, November, &c. It is not meridianally symmetrical.
