Abstract
This paper is to define a fragment of the architectural theory of Antonio Gaudi y Cornet (1852-1926) by elucidating the meaning of ornamentation in his unpublished 『Notebook containing diary and notes on "Ornamentation"』written by himself during 1876-1879. The followings have been proved, 1) First of all the importance of this material has been defined by considering historically many literatures of Antonio Gaudi. This material has been neglected by many traditional biographers for a long time. 2) This one was not manuscript on ornamentation written as general consideration, but manifestation of architectural vision that Gaudi himself imposed through the process of investigating the sense of crnamentation. 3) In this notebook Gaudi grasped extensiveely the meaning of ornamentation as the process of synthesizing the architecture in itself, or vital 「synthetic form」(the original pp.63), 「simplified form」(the original pp.63) produced from this process. 4) The concept of synthesis, that had been grasped in form of 「embryo」(the original pp.62) in this notebook, was maintained preciously in his mind, raised and succeeded to the ripeness of the synthesis in his later years (1914-1926), which characterized the figure and works of Antonio Gaudi.
