Prior to the studies of Sediyo-father, they thought that the Arabs were engaged only in checking the tables of Ptolemy , changing nothing in his theories and adding nothing to them. He was first convinced of the fallacy of this opinion. Opening in the Leiden library in the Arabic manuscript the works of Ibn-Shatir 25 unknown before that time, the heads of the work of Ibn-Younis , Sediyo first learned from them about the level of development of Arabic trigonometry. He proved that the star catalog of Ulug-Beg is a completely original work, compiled on the basis of new observations of stars. As for the other Arab star catalogs, they all turned out to be simple lists of the Ptolemy catalog. Sediyo also discovered the works of about the gnomonics of the Arabs.
Sedillo died in Paris from a cholera epidemic.
