Explanation: One of Giorgio Vasari's important contributions to the development of art history was his work: The Lives of the Most Eminent Painters, Sculptors and Architects, first published in 1550. In this book, Vasari introduced the biographical approach to studying the works and styles of different artists and traced the evolution of art from the Middle Ages to the Renaissance. He also promoted the idea of Florentine superiority in the visual arts and praised Michelangelo as the epitome of artistic excellence. Vasari's book is considered the ideological foundation of all art-historical writing and a seminal document for the modern discipline of art history.
