But there was one misgiving: It seemed to me that I was better qualified for drawing than for painting, especially in the various branches of architectural drawing. At the same time my interest in architecture was constantly increasing. And I advanced in this direction at a still more rapid pace after my first visit to Vienna, which lasted two weeks. I was not yet sixteen years old. I went to the Hof Museum to study the paintings in the art gallery there; but the building itself captured almost all my interest, from early morning until late at night I spent all my time visiting the various public buildings. And it was the buildings themselves that were always the principal attraction for me. For hours and hours I could stand in wonderment before the Opera and the Parliament. The whole Ring Strasse had a magic effect upon me, as if it were a scene from the Thousand-and-one-Nights.
