For a new interpretation of the reverse types of 520 et 511, see M. Feugère, ‘Les bronzes de Nîmes BN 2725 et 2735 et le sanctuaire guérisseur de Nemausus’, in Histoire, Espaces et Marges de l’Antiquité, I. Hommages à Monique Clavel-Lévêque (Besançon, 2003), pp. 227-231. Feugère interprets the type of 521 as a cupping glass and the palms as the symbol of Apollo. The female figure on 520 is Hygeia. Both types are related to the sanctuary of the fountain of Nîmes whose healing waters were renowned.
