Ibn Bajja

Abu Bakr ibn Bajja (d. 533 AH / 1138–1139 CE) was an Andalusian philosopher, physician, mathematician, and poet, renowned for his philosophical writings such as Tadbir al-mutawahhid (The Governance of the Solitary) and his mastery of music and logic Mujam Tarikh al-Turath al…+1.

Lineage and Early Life

He was Abu Bakr Muhammad ibn Yahya ibn al-Sa'igh al-Tujibi al-Andalusi al-Saraqusti, widely known as Ibn Bajja (and in the West as Avempace) and also as Ibn al-Sa'igh Mujam Tarikh al-Turath al…+1. The term bajja reportedly signified silver in the Romance vernacular of the western Islamic lands Tarikh al-Islam+1. He was born in Zaragoza toward the end of the fifth century AH during the latter era of the Hudid dynasty Mujam al-Muallifin+1.

Political Career and Travels

Ibn Bajja rose to prominence in Zaragoza, where the Almoravid governor Abu Bakr ibn Ibrahim ibn Tifilwit appointed him as his vizier Tarikh al-Arab wa Hadhara…+1. A celebrated anecdote relates that Ibn Bajja composed and set to music a muwashshah in praise of Ibn Tifilwit; upon hearing its concluding lines, the governor was so delighted that he tore his robes and swore an oath that Ibn Bajja would walk back to his residence only upon gold, whereupon the philosopher placed gold inside his sandals to fulfill the oath without extravagance Nafh al-Tib min Ghusn al-…+1.

Following the Christian conquest of Zaragoza in 512 AH, Ibn Bajja relocated southward, staying in Seville and Xàtiva before migrating to the Maghrib Tarikh al-Islam+1. In North Africa, he served as vizier to the Almoravid prince Yahya ibn Yusuf for twenty years al-Mawsua al-Muyassara fi….

Scholarly Standing and Students

Ibn Bajja was widely recognized as a leading figure in Andalusian philosophy, mathematics, astronomy, and music theory Siyar Aalam al-Nubala+1. Ibn al-Khatib described him as the last of the major Islamic philosophers of al-Andalus al-Mawsua al-Muyassara fi…+1. His student Abu al-Hasan Ibn al-Imam al-Katib assembled his philosophical treatises—including works on the intellect such as Ittisal al-aql bi-l-insan (Conjunction of the Intellect with Man)—and observed that Ibn Bajja’s direct grasp of Aristotle surpassed that of Ibn Sina and al-Ghazali, placing his standing alongside al-Farabi Mujam Tarikh al-Turath al…+1. Later philosophers such as Ibn Rushd drew substantially upon his thought, and among his pupils in musical composition and performance were Abu Amir Muhammad ibn al-Himmara al-Gharnati and Ishaq ibn Sham'un al-Qurtubi Siyar Aalam al-Nubala+1.

Controversies and Death

Ibn Bajja’s philosophical pursuits drew intense hostility from traditionalist and rival contemporaries. The anthologist Ibn Khaqan leveled fierce accusations against his religious orthodoxy and personal conduct in Qala'id al-iqyan, alleging heresy, negligence of religious duties, and planetary determinism, though Ibn Khaqan subsequently offered glowing praise of his intellect and learning in Matmah al-anfus after Ibn Bajja sent him financial gifts to appease him al-Mawsua al-Muyassara fi…+1.

Hostility from professional competitors persisted, and multiple attempts were made against his life Siyar Aalam al-Nubala+1. Ibn Bajja died of poison in Fez in 533 AH (1138/1139 CE) before reaching old age, an assassination attributed by historical accounts to the envy of rival physicians Mujam al-Muallifin+1.
