If Herodotus borrowed from Homer the way the later tradition of historical battle description described fighting, adapted the array of the armies from the Homeric catalogue, and himself invented the ‘weighing’, the historian's declaration about why one side defeated the other, Thucydides was the creator of the battle speech – the paraklēsis or parainesis, cohortatio in Latin – that so frequently became a part of the depiction of ancient battles. There is, of course, a great deal of incidental talking and encouragement during fighting in Homer, and many of the sentiments that later authors were to use can be found in Homer as well. Herodotus borrowed from him the habit of including incidental snippets of encouragement before or during battles by the way (6.11, 8.83, 9.17–18, 9.42), and the habit was adopted here and there in later authors, and especially by Livy. So similarly the epipōleēsis, the general's going along the ranks of his army and addressing a few appropriate remarks to each different contingent: this imitated Agamemnon's tour of his forces in Book IV of the Iliad, and was to have a long life in historical authors.
