Renowned architect Frank Lloyd Wright asserted, "Architecture is the mother of art. Without an architectural style of our own, we do not have the soul of our civilization."

Architectural styles, evolving over time, reflect cultural shifts, blending, borrowing, or contradicting.

Ancient Egyptian architecture emphasized harmony with the landscape, as seen notably in the pyramids of the Old and Middle Kingdoms. Ancient Greek architecture, flourishing from 850 B.C. to 600 B.C., featured three column types: Doric, Ionic, and Corinthian. 

Inca architecture showcased Machu Picchu, balancing atop the Andes. Art Nouveau, a short-lived but influential movement from the 1890s to 1914, embraced uniqueness and modernity, departing from Victorian-era excess.

Architecture, as articulated by Frank Lloyd Wright, emerges as the soul of civilization. It evolves, mirroring cultural nuances, with styles either converging, diverging, or metamorphosing over time. Ancient Egyptian architecture epitomized this synthesis, emphasizing symbiosis with the surroundings. 

The pyramids, notably the Great Pyramid of Giza, stand testament to an era where structures embodied both earthly and divine connections.

Transitioning to Ancient Greece (850 B.C. to 600 B.C.), architectural finesse reached new heights. A well-defined system of rules governs structures, with columns (Doric, Ionic, and Corinthian) serving as iconic elements. Theaters, paramount in Greek architecture, mastered optical illusions and balanced proportions, becoming timeless embodiments of aesthetic precision.

In the heart of the Andes, the Inca city of Machu Picchu attests to architectural ingenuity. Perched at 8,047 feet, it blends seamlessly with the mountainous landscape, a testament to the harmonious coexistence of human creation and natural grandeur. A journey here mandates acclimatization, underscoring the profound connection between architecture and the environment.

Shifting to Dhaka, Bangladesh, the National Assembly boasts an octagonal structure surrounded by geometric forms—circles, squares, and triangles. A unique blend of modernity and tradition, this architectural marvel stands as a symbol of political and artistic convergence.

Kang, a proponent of timeless design, left an indelible mark on Roman architecture. His legacy, embodied in a structure crafted by local hands over 23 years, endures as a testament to the pursuit of immortality through architecture.

Venturing into the late 19th and early 20th centuries, the Art Nouveau movement emerged. A reaction against Victorian excess, it sought uniqueness and modern expression across Europe and the Americas.

Architects and designers embraced asymmetry, free curves, and natural forms, departing from historical replicas. This brief yet impactful movement laid the foundation for modern architectural philosophies, challenging conventions and influencing the course of design history.

In the intricate tapestry of architectural evolution, each style is a chapter, distinct yet interconnected. Wright's assertion reverberates through time, urging us to recognize architecture as the custodian of cultural identity.

As styles transcend eras, the conversation between past and present, tradition and innovation, continues. It is within this dialogue that the soul of civilization finds its most resonant expression, embedded in the bricks and mortar that shape our built environment.

Delving further into architectural epochs, the profound impact of Art Nouveau from the 1890s to 1914 becomes evident.

This movement, resonating across continents, sought to break free from Victorian ornamentation, embracing asymmetry and organic forms. Architects and designers aspired to create unique expressions, ushering in a departure from historical replicas.

The Art Nouveau era, though fleeting, left an indelible mark on the design landscape, influencing subsequent architectural philosophies.
