Keeping an eye on publications:
Guido, L. 2009 'I Numina Diuorum Augustorum e la Legio XX Valeria Victrix: una nuova iscrizione da Aquisgrana', Latomus 68, 644-656
My eyes lit up at the words 'nuova iscrizione' but a little investigation establishes that Aquisgrana is in fact the Italian name for Aachen and this is again the dedication by Julia Tiberina, wife of Q Iulius [Fl]avus mentioned herein once or twice. I may have time to get up to the university library when I'm in Nottingham tomorrow...
