Answer 2

Answer:

2. Bramante

Explanation:

     Mannerist architecture is born out of the tradition established by Renaissance architects such as Alberti, Filippo Brunelleschi and Bramante in the 15th and early 16th centuries, who drew their inspiration mainly from ancient treaty writers such as Vitruvius and the Roman ruins, which remained visible since antiquity and served as a memento perennial of the great classic past, whose influence was never lost at all for the Italians.

    The perspective developed in the 15th century and the growing importance of drawing as an aid to knowledge were fundamental elements for the development of the classicist architectural style, which reached a high point in works such as the Pazzi Chapel and Bramante's Tempietto, which enshrined the system of proportions and the organization of the typical spaces of the High Renaissance.
