Abstract
This paper is the first part of the thesis on the theory of J. -N. -L. Durand's architectural education at the Ecole polytechnique. Precise examination of the policy and the system of the school education informed mainly by the official documents reveals that the architectural course in the Ecole at that time was well established for all engineering students who were destined to work for various kinds of the government services. Durand's architectural education, which chiefly consisted of lectures and drawings, accomplished such a basic architectural training according to the Ecole polytechnique.
