Romaka siddhanta has been a vital Siddhanta to calculate the mean of the Sun and the moon which differed with small equation with that of Ptolemy. Romaka Siddhanta has been more successful in calculating the equation of the Sun and the moon where the difference between the longitude of the mean sun and the longitude of the apogee is stated as 75 degree which is different from that of Ptolemy who calculated it as 65 degree30 inches. The following equation of the centre of the sun and the moon comes after every 15 degrees. Romaka Siddhanta has been one of the most vital source of Indian Astronomy which has been able to distinctively mark the latitudes as well as longitudes of the Son as we'll as the moon and mark out the other details regarding the solar system. Romaka Siddhanta which is the second Siddhanta of Astronomical Siddhantas in Ancient Indian Astronomy contains some doubts regarding its author where it has sometimes been associated with Srisena which some recognise it as the original work Brahmagupta. With a careful study it has been revealed as the original work has been much influenced by the innovations of Varahamihira- one of prominent Hindu Astronomer which has been the only astronomical work which is based on tropical studies and which has been considered as one of the Five Astronomical Cannons of Fifth century. The Romaka Siddhanta is thus the second most important astronomical methodology which is based on ancient Indian mathametics. Influenced with the Roman mathematics this has proved to be more accurate in locating the position of the Sun and the Moon with their longitudes and latitudes. |
