The Commands & Colors: Ancients module now displays cards in Italian when configured appropriately. Download the latest version here
To view, select the Italian Language option from the Preferences…General tab:
Note: Only cards and standard Vassal menus are translated.
Thanks to @alecrespi for providing the translated card images.
Compatibility
Broadly compatible with previous v4.3 releases but, for best reliability, all players should use the same module and Vassal version. Not backward compatible with releases prior to v4.3, except for viewing v4 games. Requires Vassal v3.7.12 or later.
