Kitāb Arshimīdas fī al-binkāmāt كتاب أرشميدس في البنكامات Archimedes أرشميدس [‎19v] (36/39)

Content

Treatise on the hydraulic and pneumatic machinery of water-clocks with thirteen diagrams, attributed to Archimedes (Ἀρχιμήδης; أرشميدس; fl. 3rd century BC). The title is given wrongly as كتاب أرشميدش في عمل السكامات ( Kitāb Arshimīdash fī ‘amal al-sakāmāt ; f. 2v, line 1); the final word should read البنكامات ( al-binkāmāt , 'water-clocks'). The treatise is a compilation material from Greek, Byzantine, Persian and Arabic sources, and some sections may in fact be derived from Archimedes.

Begins (f. 2v, lines 3-6):

إذا أردت ذلك فاعمد إلى نحاس فاتخذ منه خزانة

للماء (!) يكون ارتفاعها ثلثة أشبار في شبرين وليكن

مدورة مستويه مهتدمة جيدة اللحام وليكن لها

قوائم ...

Ends (f. 21r, lines 7-11):

... فنركب القمع في طرف الأنبوب من خارج ونصب

الماء حتى يبلغ المقدار الذي يراد منها الذي وصفناه فيما

تقدم من عملها إن شاء الله وقد يستخرج من هذه الآلة آلات

كبيرة فافهم ما وصفناه ولا قوة إلا بالله ثم ما أردنا من

ذلك وبالله التوفيق ...
