Here two wedge holes have been carved out while one has only been roughly outlined with the point chisel. Clearly work was abandoned before all of the wedge holes had been prepared.
The aim here was to split the rock using this row of wedge holes and the row above these but work was abandoned before the wedges themselves were employed.
Notes
This is one of the more than seventy individual extraction points which constitute the so-called City Quarries at Aphrodisias, located roughly 2 km north of the city. White and grey marbles were quarried in this area.
