Answer
Ammonius Saccas was an Egyptian philosopher who lived in the 2nd-3rd century AD. He is often considered to be the founder of Neoplatonism, a school of philosophy that combined elements of Plato's philosophy with ideas from other schools of thought, such as Stoicism and Aristotelianism. Saccas' teachings were passed on to his students, including Plotinus, who further developed Neoplatonism into a major philosophical movement.
