Of Alexandria, a Jew by birth who publicly renounced his relationship with the Jews according to their custom by driving the white donkey through what they call the synagogue on the day of rest. This Zeno was a good and pious man by nature, but rather slow in literature and learning. He always desired to learn something and kept asking questions about what he did not know, but remained almost completely ignorant. He was very dull in understanding; those things which he finally managed to learn he quickly betrayed through forgetfulness.[1] There was also another Zeno, a companion of Proklos, living at the same time, a Pergamene by birth; he also was rather deficient in natural ability as far as knowledge is concerned; but he was good and well-disciplined in character. Which of these two [Zenos] provided Sallustius with the cause of his dispute with Proklos I am not able to say.[2]
