For the Greeks, "signs" occurred in the world of nature, "symbols" in the world of culture. Not until Augustine of Hippo would a thematic proposal for uniting the two under the notion of "sign" (signum) as transcending the nature-culture divide and identifying symbols as no more than a species (or sub-species) of signum be formally proposed. See the monograph study on this question, Le teorie del segno nell'antichità classica by Giovanni Manetti (Milan: Bompiani, 1987); trans. by Christine Richardson as Theories of the Sign in Classical Antiquity (Bloomington, IN: Indiana University Press, 1993). Classic also is the article by Luigi Romeo, "The Derivation of 'Semiotics' through the History of the Discipline", in Semiosis 6, Heft 2 (1977), 37–49. See also Andrew LaVelle's discussion of Romeo on Peirce-l at [1].
