This paper examines next four points of the Francesco di Giorgio's urban theory; 1) the nature and the status of man in the nature 2) man as the "piccolo mondo" 3) city and man as "social animal" 4) the urban structure and the "corpo umano". The superiority of man in the nature, he insists, is based on operations and arts by means of the intellect, reason and the hand. Especially he admires the hand as the organ of organs, the instrument of instruments. This evaluation of man and his technological ability is essential in his urban theory. In addition to the above mentioned, he insists, man has a perfect body and he regards man as an autonomical "piccolo mondo", similar to God. Instruments and obejects are made on the model of the perfect body. From this, as the extention of instruments, a city can also be constructed on this model. A city is regarded as an Unity which is consisted of man as "animale sociabile". This means that in a city, as Aristotle describes, man can become human being in the true sense. Citing the Dinocrates's anecdote from Vitruvius, he declares that a city shoud be structured based on the proportions and relations of the body, on the analogy of its form and function.
