Similitudinem quidem immensa reputatio est (NH VII, 52). Evocazione, assimilazione, sovrapposizione nella ritrattistica monetale antica

[Autom. eng. transl.] The contribution studies the phenomenon of similitude in ancient coin portraiture, that is of the resemblance that, in a more or less evident way, can be seen among portraits of different characters imprinted on the coins. The reflections on different categories of similarities - men-like women, men similar to other men, men transformed into women to cite only some examples - lead the author to formulate hypotheses about the motivations of these, very distinct, similarities. Some somatic resemblances could relate to the ideology of power and reflect a political situation, others being of a purely genealogical type or, again, simply reconstructed on the basis of an already existing image due to the lack of a prototype.
