The ancient culture known for its contributions to mathematics and architecture is the Ancient Greeks. They made significant advancements in various mathematical concepts, including geometry, algebra, and the development of mathematical proofs. Figures such as Euclid, Pythagoras, and Archimedes laid the groundwork for modern mathematics. Architecturally, the Greeks are renowned for their monumental structures, such as the Parthenon, which exemplified their mastery of design, symmetry, and proportion. Their contributions to both mathematics and architecture not only influenced subsequent civilizations but also established foundational principles that continue to be fundamental in various fields today.
