Jamal al-Din al-Watwat

Jamāl al-Dīn Muḥammad ibn Ibrāhīm ibn Yaḥyā al-Kutubi (جمال الدين، محمد بن إبراهيم بن يحيى بن علي المروي الأنصاري، الوراق الكتبي), known as al-Waṭwāṭ (الوطواط, 'the bat', 632-718 AH/1235-1318 CE) was a scholar and bookseller; he was born and died in Cairo.

Works and editions
Al-Waṭwāṭ's works include:
 * غرر الخصائص الواضحة وعرر النقائص الفاضحة
 * مباهج الفكر ومناهج العبر (Mabāhij al-fikar wa manāhij al-ʿibar, 'Delightful Concepts and the Path to Precepts'). The fourth section on this work was the first original Arabic work on agriculture since Ibn Wahshiyya's tenth-century Kitāb al-Filāḥa al-Nabaṭiyya, of which al-Waṭwāṭ made extensive use.
