Ptolemy'S "Tetrabiblos" In The Translation Of William Of Moerbeke

This is the first edition of Moerbeke's Latin translation of Ptolemy’s celebrated astrological handbook, known under the title Tetrabiblos or Quadripartitum (opus). Ptolemy’s treatise (composed after 141 AD) offers a systematic overview of astrological science and had, together with his Almagest, an enormous influence up until the 17th century.
