"They are powerful signs, those that Garau wanted to paint. They are the reconnection of a tradition that has its roots in the best Renaissance and even earlier in Italian sacred art but revisiting it in a contemporary, not to say futuristic, key. They are a reflection on what the transcendent is: on this or other planets, even if there were other intelligences, the question of what is not visible would still arise. It is the attempt of art to suggest more than answers, the eternal questioning."
