Abstract
In “Die Weltbaumeister”, a book of architectural drama of the collapse and the rebirth of architecture published by Bruno Taut in 1920, three types of formal languages are found through the formal analysis of all pictures in the book, namely historical forms, vegetable forms and crystal forms. The system integrating all those types were especially found in the total form of his image of “Crystal House”. This paper has clarified this book shows Taut's thought about metamorphose of architectural forms, and is a relevant material to understand how his utopian architectural forms were generated around 1920.
