The Alexandrian Philosopher Anonymous was a thinker active in Alexandria, Egypt, likely during the 1st century BCE, though this dating remains uncertain. He is known solely for a single surviving work: a set of notes or scholia on Aristotle's Categories. This text is preserved within the collected commentaries of the later philosopher Alexander of Aphrodisias.
The author's background is unclear, and available sources treat the work as a standard piece of Aristotelian philosophy without noting any specific religious or cultural affiliation. His notes show how Aristotle's logic was taught and debated in the Hellenistic period, particularly within the intellectual centre of Alexandria.
The work is a link in the early reception of Aristotle's thought, showing how core philosophical concepts were interpreted in the centuries before the great commentators of late antiquity. It helps trace the development of Peripatetic school traditions and philosophical terminology.
