Diogenes Laertius Vitae philosophorum 4.6.39

[39] And whereas many persons courted Antigonus and went to meet him whenever he came to Athens, Arcesilaus remained at home, not wishing to thrust himself upon his acquaintance. He was on the best of terms with Hierocles, the commandant in Munichia and Piraeus, and at every festival would go down to see him. And though Hierocles joined in urging him to pay his respects to Antigonus, he was not prevailed upon, but, after going as far as the gates, turned back. And after the battle at sea, ¹ when many went to Antigonus or wrote him flattering letters, he held his peace. However, on behalf of his native city, he did go to Demetrias as envoy to Antigonus, but failed in his mission. He spent his time wholly in the Academy, shunning politics.
