Hayʾat al-aflāk






This text describes both the celestial and terrestrial realms. A codex table of contents (Oxford, Bodleian Library, Seld. 11) attributes the work to Qusṭā ibn Lūqā. But this t of c and the attribution are in a different hand than the witness itself and the text itself is anonymous. A passage from the work using the distance between Palmyra and Raqqa to find the size of the Earth is found in Damascus, Ẓāhiriyya 4489, f. 12a-b, where it is attributed to Muḥammad ibn Mūsā under the title “Ḥarakat al-aflāk”, which see.
