The claim about this work being a synthesis of Almagest with Arabic tradition is untrue. Almagest had a great influence on arabic tradition, but the subject of this book has very little overlap with Almagest - that book is about the motion of the Moon primarily and also of planets, which is the opposite "Fixed Stars" which this book is about. I propose to remove this phrasing. Kotika98 (talk) 14:04, 6 March 2014 (UTC)
