(Δείνων), one of the chief men of Rhodes, who, when the war broke out between Perseus and the Romans (B. C. 171), vainly endeavoured to induce his countrymen to pay no regard to the letter which C. Lucretius had sent to ask for ships, and which Deinon pretended was a forgery of their enemy Eumenes, king of Pergamus, designed to involve them in a ruinous war. But, though he failed on this occasion, he still kept up a strong opposition to the Roman party. In B. C. 167, after the defeat of Perseus, the Rhodians delivered him up to the Romans by way of propitiating them. Polybius calls him a bold and covetous adventurer, and censures him for what he considers an unmanly clinging to life after the ruin of his fortunes. (Plb. 27.6,11, 28.2, 29.5, 30.6_8; Liv. 44.23, 29, 45.22.)
