His power of patient endurance, or perhaps his slowness, earned him the title of "the Ass" from his fellow students, a name which he was said to have rejoiced in, as it implied that his back was strong enough to bear whatever Zeno put upon it.
Hans förmåga till tålmodigt uthärdande, eller kanske hans långsamhet, gav honom öknamnet "Åsnan" bland sina medstudenter - ett namn som han sägs ha varit glad åt, eftersom det visade att hans rygg var stark nog att bära vad än Zenon lastade på den.
