I find it interesting how the eyes are carved in relief to give the appearance of shadow and reflection (note the little protruding tubercle to simulate a "glint"). Presumably in classical statuary the eyes were either painted to create those effects or replaced with jewels/stones.

You should see the various veiled virgin sculptures to see amazing examples of stone shaped into an illusory form:

Thank you for that. It's a truly marvellous piece of work!
