Abū Muḥammad al-Ḥasan ibn Aḥmad ibn Yaʿqūb al-Hamdānī (Arabic: أبو محمد الحسن بن أحمد بن يعقوب الهمداني, 279/280-333/334 A.H.; c. 893 – 947;) was an Arab[1] Muslim geographer, chemist, poet, grammarian, historian, and astronomer, from the tribe of Banu Hamdan, western 'Amran, Yemen.
He was held in high repute as a grammarian, wrote much poetry, compiled astronomical tables and is said to have devoted most of his life to the study of the ancient history and geography of Arabia.
