f. 61b begings with nine lines taken from an introduction to astronomy with the title
Muqaddima fī ʿilm al-falak. These are followed by another seven lines from another
work on stars. All these lines are written by one copyist. Directly following are
two paragraphs written by a second copyist. The text on ff. 61b-62a deals with the
implementation of a leap year every 12th year, since scholars do calculate the xears
according to the solar calendar, the months according to the lunar calendar. The leap
years are named after animals. This is illustrated in a circle with notes in three
languages, Arabic, Persian, and Ottoman-Turkish. ff. 62b-63a deal with the stars.
It canʾt be judged with certainty in how far all these text passages originally belong
together. The margins of f. 62a and f. 63b have collation notes of each of the copyists. f. 64a: باب في معرفة كسوف القمر ff. 65a-74a: اسماء الكواكب f. 74b: ? f. 75a: اذا اردت ان تقلب منكبنا من الزوال; the entry has been written by Muṣṭafā الحرطاجى
in the year 1081/1670-1671. f. 75b: جدول حدود قوس مقام روية العلال
f. 61b: مقدمة فى علم الفلك اعلم ان علم الفلك صناعة نظرية ينظر منه في حركات الاحرام العلوية
... بسم الله الرحمن الرحيم الحمد لله العليم العلام العزيز الذي لا يرام كاشف علم النجوم
والاحكام للنبي ادريس عليه السلام ... وبعد فاعلم انها الاخ العزيز واللهف الحريز ان
للحكما خطا وختن وترك ومغلول والغور قاعدة وحسابا وتاريخا وذلك ان سنينهم شمسية وشهورهم
قمرية فكل اثنى عشرة سنة عندهم دورا واحدا

f. 63b: فلا يبقي موضع مكشوف موازلها الا واخذ منها خطه وتميل مرة الي الجنوب ومرة الي الشمال
لتعم فايدتها والله تعالي اعلم بالصواب تمت
