There are four rotational knobs. The knobs were added after the rete was engraved. Finally, the star pointer for الحاوا (?) has been repaired and the name obscured..The star pointer for الدبران is a subtle profile of a bird.The zodiac on the rete is labelled: الحمل , الثور , الجوزا , السرطان , الاسد , السنبله , الميزان , العقرب , القوس , الجدي , الدلو , الحوت
