"Look for the jewel set in the heart of the city, where stone is not just stone." The map also gave me an address: Corso Ercole I d'Este, 21, 44121 Ferrara, Italy. I have to leave the garden and reach it because that is where I have to look, "walking" through the streets. I am so curious but the directions are vague: the sun, opposite, points to what is doubly right. What does it mean? I must observe carefully. Only by looking at things from all perspectives can I find the answer.
