With regard to astrology, Vitruvius’ interest becomes outwardly visible in his discussion of sundials, instruments through which “the east and the west, the south, the north, and the turning of the heavens” may be discerned. Without such knowledge, he observes, “the rules of sundials cannot be understood in any way.” His decision to close the chapter with a programmatic declaration — “I promise, and I hope, to present them in these volumes with the greatest competence and without hesitation, not only to builders but also to all learned men” — reveals a broader ambition: Vitruvius does not address technicians alone, but outlines a dual vision of architecture, where practical knowledge intertwines with a speculative dimension intended for an educated audience.The rules governing sundials underscore their significance in an era that conceived these instruments as projections of the cosmos upon the earth. The shadow cast by a simple gnomon could define a space in correspondence with the planets and in harmony with the “music of numbers” sustaining the geometry of architectural works. Vitruvius consistently preserves this cosmic dimension, much like the priests of Alexandria, who impressed upon the world a trace of their knowledge — a trace that later became a pillar of our cultural tradition.Ultimately, the interaction between arts and sciences, understood as a synthesis of human expression, finds full justification in Vitruvius’ work, albeit across centuries and not without interpretive challenges. The deciphering of hidden terminologies remains an obstacle to the immediate use of his notions, yet it does not diminish the theoretical scope of a work that, despite its fragmentary nature, preserves a complex vision of architectural practice, where technical knowledge rests upon a symbolic and cosmological substratum.
