• 300s B.C. - Troy linked as Rome's mother city by late century
• 200s-100s B.C. - Roma shown with Phrygian cap, sign of Trojan status
• 205 B.C. - Cult of Cybele & Attis imported, enshrined in the southwest corner of the Palatine hill, overlooking the Circus Maximus
• 100s B.C. - Battle paintings of conquered easterners feature in triumphal processions, iconography now negative
• 45/46 B.C. - Julius Caesar “revives” the lusus troiae, an equestrian parade and mock battle staged by patrician youths in the Circus Maximus; their garb mimicked priests of the cult of Cybele
• 2 B.C. - Fixed iconography for Aeneas and Ascanius emerges. Aeneas as a contemporary Roman general in full armor, Ascanius as an easterner with trousers and cap. The costume was confined to children in public displays, and Aeneas never shown in it until late antiquity.
