Bernard Rudofsky was among the first to introduce an open criticism of the formal in architecture in the international theoretical debate. Through the exaltation of the vernacular construction, he divulged directly and without mediation, a radically different informal architecture which could be adopted as a reference. His position is innovative because it is poetic, based on a vision of the vernacular as an a-top, a-starch, a-critic, general and global category: “Vernacular architecture owes its spectacular longevity to a constant redistribution of hard-won knowledge, channeled into quasi-instinctive reactions to the outer world”.
