Ah the memories:
"This might be the strongest, most compelling sculpture at the Met. The subjects don't necessarily look like they are starving to death, but the emotion caught in marble is tight. Look at Ugolino's feet, and the despair, fear, and need on his eldest son (to the left). Complicated and amazingly carved, this depicts the story from Dante's Inferno, where Ugolino was locked in a tower with his sons and given no food."
"Carpeuax's sculpture is often used as a political metaphor."
