Since we don't know the actual name of the "Unknown Roman Artist," we can ironically call their style "Veristic Vagueness."
Style: Focused on hyper-realistic depictions of individuals, particularly emphasizing age, wrinkles, and imperfections. Meant to convey seriousness, experience, and virtue.
Key Characteristics: Deep wrinkles, sagging skin, balding heads, strong brow lines.
Themes: Ancestral respect (Roman values), civic duty, wisdom gained with age, the power of experience.
So, "Veristic Vagueness" because while the veristic (hyper-realistic) style is evident, the vagueness surrounding the artist's identity reminds us we don't even know who to attribute these striking portraits to!
