The various assertions about the conception of the cosmos, or even of the universe, in its human form refer to the old necessity of presuming and prescribing the relation between the unknowable and its terrestrial instance, man. Within this complex and interwoven set of astral elements comes the idea of the cosmic man [homo cosmicus] imbricated with the theories of the macrocosm and microcosm, which would naturally be the one that would assimilate the anthropomorphic structures behind the firmament and, above all, creation. This structure will be responsible for the emergence of an iconographic topos that will represent and amalgamate a whole place of development of particular knowledge, such as medicine and the astrological, theological, philosophical, etc. elements. In this article we try to understand how the survival of the theories of the macrocosm and microcosm was constituted as a topical development in the European Middle Ages, with the figure of man as the main element being used as a proportion for all things. The image of this man is defended by the clash between dialectics and rhetoric and has as its basic structure the metaphorical regime constituted by the analogy.
