Albategnius, Or Albategni (Properly Mohammed Ben Geber Albatani), an Arabian prince and astronomer, died about A. D. 929. He is also called Muhamedes Aractsnsis. His principal astronomical work - mainly an abridgment of the Almagest of Ptolemy, though containing many original principles and observations - was translated into Latin by Plato of Tibur, and published at Nuremberg in 1537, and afterward at Bologna in 1645. In the opinion of Lalande, he was one of the 20 most eminent astronomers that ever lived.
