Towards the end of 2020, while doing some work on a college research paper, I found an image of Epictetus I had never seen before. I was exploring my college's various research engines and one of my searches yielded an image from the British Museum; an drawing of Epictetus.
You can find the print here: https://www.britishmuseum.org/collection/object/P_1935-0828-5
The description states, "Epictetus: bearded man seen head and shoulders, head resting on his left hand; on white ground; detail from the School of Athens, after Raphael"
- Zeno of Citium
