How did John Ruskin describe the history of Venice in The Stones of Venice?

In his three-volume treatise The Stones of Venice, John Ruskin presents the history of Venice as a moral and social narrative structured like a sublime epic.12

Ruskin charts the city’s history through three distinct stages:

• The Foundations: The first volume provides a historical overview and establishes the functional and ornamental principles of architecture.1
• The Sea Stories: The second volume highlights the Byzantine period and the climactic development of Venetian life during the Gothic era, which Ruskin viewed as an expression of pure national faith and domestic virtue.1
• The Fall: The third volume argues that the onset of the Renaissance initiated the city's architectural and moral decline, representing concealed infidelity and domestic corruption.1

Ultimately, Ruskin portrays the trajectory of Venice as a fall from a medieval "Eden" into a modern state of political impotence and social frivolity, maintaining that the city's architecture served as a direct reflection of its underlying social and moral conditions.2
