Long before Thomas Hobbes wrote systematic works on political philosophy, he produced the first English translation of Thucydides’ History of the Peloponnesian War directly from Greek. Published in 1629, it was a result of several of his formative years spent in Thucydides’ close company. Starting from the premise that such an experience could have informed Hobbes’s own ideas to a certain extent, this article tries to establish points of connection between Thucydides’ text and Hobbes’s conception of the state of nature. The aim is to identify ideas that might be at work behind different aspects of one of the focal points of Hobbes’s political thought. The analysis begins with Thucydides’ Archaeology depicting the manner of life of the ancient Hellenes; moves to ‘the three greatest things’ that, working on both individual and collective levels, impelled Athens to build an Empire and consequently trigger the war with Sparta; subsequently turns to the disintegration of Corcyraean polis during stasis; and in the end engages with the same problem that in Athens was caused by the plague.
