The exhibition rooms in Palazzo Mazzetti in Asti are displaying the works of Escher, the artistic genius and visionary, and a favourite with the general public around the planet. Iconic among art lovers but also among mathematicians, designers, and graphic artists, his unique creations combine art with the universe of numbers, science with nature, and reality with imagination, generating fanciful inventions and paradoxes both magical and marked by strong scientific rigour.
