Abstract: | The astronomical tables compiled by Muslim astronomers in the medieval period are based on the sexagesimal system, and to facilitate their computations these astronomers used multiplication tables displaying products expressed sexagesimally. In a recent publication these tables were described for the first time. The present paper points to the existence of more of these tables, as well as to tables displaying sexagesimal quotients and others for facilitating linear interpolation. |
