Proposition 8 from Book 1 of Gnomonices libri octo (Rome: Apud F. Zanettum, 1581, pp. 26-37) by Christophorus Clavius (Christoph Klau; كلاويوس; 1538-1612; see fol. 3r, line 9), translated into Arabic by Rustam Beg al-Ḥārithī al-Badakhshī ibn Qubād Beg, titled Dīyānat Khān (رستم بيك الحارثي البدخشي بن قباد بيك المخاطب بديانت خان; d. 1705, see fol. 2v, lines 5 and colophon Section at the end of a manuscript text. fol. 22r, lines 9-10, transcribed below), a courtier to the Mughal emperor Aurangzeb (reg. 1658-1707). The rough draft of al-Badakhshī's translation by the hand of the translator is preserved in MS IO Islamic 1308, but there Book 1, Proposition 8 is omitted (see fol. 12r). This is likely to be because the translator had previously translated this proposition separately, since he says in the preface that his attention was drawn to Clavius' Gnomonices by his father, Mīrzā A title of honour originally applied to princes, later to military leaders, and later still to secretaries, chieftains, and other ‘gentlemen’. Qubād Beg (see fol. 2v, line 8), who was interested in conic sections, the topic of Proposition 8.

The translator also explains that he has appended similar material, and this is found in the form of four excerpts from Clavius' Euclidis elementorum libri VI (Rome: apud Vincentium Accoltum, 1574): Proposition 4, Book 6 (ff. 19v-20r); Prop. 13, Bk 6 (ff. 20r-20v); Prop. 4, Bk 2 (ff. 20v-21r); Prop. 79, Bk 10 (ff. 21r-21v); and Prop. 1 from Prop. 3 (?), Bk 6 (ff. 21v-22r).

Begins (fol. 2v, lines 2-5):

الحمد لله الذي انطقنا بلغات عجيبة وميزنا من أبناء الجنس بعلوم غريبة والصلوة على خير

من نبع من منبع الشرف والكمال وأشرف من طلع من مطلع الفضل والأفضال وعلى آله المرشدين

إلى الرشاد وأصحابه الهادين طريق السداد أما بعد فيقول العبد المفتقر إلى رحمة الرب

الغني رستم بيك الحارثي البدخشي إنّه لما كان قطوع المخروط من الأشكال الكثيرة الفوائد ...

Ends (fol. 22r, lines 6-8):

لأنه لما كان ط ي ك ب ح ر ح ن س متناسبة تكون السطوح المتشابهة المعمولة عليه

ي ل ب ء ر ح ط ن س ع أيضًا متناسبة ولأن ي ل عملناه مساويا لأ سطوح

أ ب ء ر ح ط ن س ع أيضًا متناسبة وهو المراد

Colophon Section at the end of a manuscript text. (fol. 22r, lines 9-10):

قد فرغ من تسويدها وتحريرها بن قباد بيك

الحارثي المخاطب بديانت خان
