It is hard to comprehend that people are so skilful as to carve this from marble or stone. I am often astounded when wandering around museums and galleries at the skill of sculptors both ancient and modern, especially in making a hard material appear so lifelike. I am with you Horacio. I particularly like to see work in progress when the human anatomy appears to be uncovered by the artist chipping away and working the marble.
Not a perfect photograph as it is a snapshot quickly taken in a gallery, but an illustration of what I am trying to express.
