On 13 August 1923 Eschers first solo exhibition opens at the ‘Circolo Artistico’ in Siena. It’s a milestone but he paid very little attention to it. He’s in love with Jetta Umiker and all his thoughts and actions are aimed at her.
After she returns to Switzerland with her parents at the end of June, they write each other long love letters. In one of them he adulates the Tuscan city, for which his infatuation is almost as large as for Jetta.
‘I love this Siena so much. A naive person would feel as a new-born here, free of all sins. If the happiness of man depends on the place he lives, i would stay in Siena forever.’
He did make this announcement for the exhibition though.
