Jebel Musa, named, according to the 14th-century Berber Muslim geographer Ibn Battuta, in honour of Musa bin Nusayr, to whom the conqueror of Andalusia Tariq ibn Ziyad owed fealty, was known to the ancient Greeks and Phoenicians as "Mount Abyla" and to the Romans as "Columna". Together with the Rock of Gibraltar to the north, it is generally identified as one of the Pillars of Hercules (this title is also claimed for Monte Hacho in the Spanish exclave of Ceuta, to the east of Jebel Musa).
