coin of Gordian III 

Editor: Here we have a coin of Gordian III from the Harvard Art Museums. It's quite small, but I'm struck by the details still visible in the profile. What do you see in this piece, focusing on its artistic merits? Curator: Observe how the coin's circular form dictates the composition. The incised portrait and lettering, while worn, adhere to the coin’s edge. The relief, however subtle, creates depth. The metal itself, corroded, speaks to time's passage. Editor: So the degradation itself becomes a part of the artwork? Curator: Precisely. The coin's materiality—its very substance and form—conveys meaning, transcending its original function. It exemplifies a unity of form and content. Editor: That's fascinating. I'll definitely look at ancient coins differently now.
