Kitāb Mānālāwus fī al-ashkāl al-kurīyah كتاب مانالاوس في الأشكال الكرية Menelaus of Alexandria مانالاوس

Content

An early copy of Muḥyī al-Dīn Yaḥyá ibn Muḥammad ibn Abī al-Shukr al-Maghribī's (محيي الدين يحيى بن محمد بن أبي الشكر المغربي; d. between 680/1281 and 690-1291) revised edition of the Arabic translation of Menelaus of Alexandria's (fl. ca AD 100) Greek treatise on spherical trigonometry known as Kitāb fī al-ashkāl al-kurīyah (كتاب في الأشكال الكرية) or simply as Kitāb al-ukar (كتاب الأكر; Sphaericorum ), based on an earlier translation by Abū ‘Abd Allāh Muḥammad ibn ‘Īsá al-Māhānī (أبو عبد الله محمد بن عيسى الماهاني; d. ca 888).

Contents:

• Chapter 1 (ff. 63v-65v);
• Chapter 2 (المقالة 2; ff. 65v-67r);
• Chapter 3 (المقالة 3; ff. 67r-v)

The text appears to be defective at its end.

Begins (f. 63b, lines 1-2):

... هذا كتاب مانالاوس في الأشكال الكرية تهذيب العبد الفقير إلى الله محمد بن أبي الشكر المغربي الشكل الأول

The script is so small and hastily written as to be almost illegible at the end.

There are 117 diagrams of triangles projected on spheres.

Folio 68r contains a diagram apparently unrelated to the texts before or after it.
