The most prominent of all is an enormous equinoctial sundial called the Samrat Yantra, a 27m-high triangular wall with two thin, semi-circular ramps that radiate like wings from its sides. Standing beneath it, my guide pointed out the shadow on one of the ramps as it moved precisely 1mm every second and indicated the local time within an accuracy of two seconds. | |
