“IL TEMPO” “MOSTRE ROMANE” – Virgilio Guzzi – April 1950

…One must appreciate the heat of the cut, the polite and sensible way of how one may feel the color, the frank and clear structure of the line. Del Sole with the lines and the vibrant colors open on the light (this is the excessive vibration that seems to have the function of suggesting the depth) resolves his forms in the plan. The order is appreciated, the reserve is also technic and that promising prudence and stylistic heat which indicates a artist already beyond of the simple naturalist emotivity.
