The Histories · 7.186

Such being the number of this body of fighting-men, the attendants who went with these and the men who were in the small vessels which carried corn, and again in the other vessels which sailed with the army, these I suppose were not less in number but more than the fighting men. I assume them to be equal in number with these, and neither at all more nor less; and so, being supposed equal in number with the fighting body, they make up the same number of myriads as they. Thus five hundred and twenty-eight myriads three thousand two hundred and twenty was the number of men whom Xerxes son of Dareios led as far as Sepias and Thermopylai.
