For decades, art historians maintained that the distinctive blue glazes in early Renaissance frescoes were derived exclusively from imported lapis lazuli, a pigment so costly that its usage was strictly dictated by wealthy patrons. However, recent spectroscopic micro-analysis of plaster fragments from mid-fifteenth-century Tuscan chapels reveals widespread trace amounts of smalt, a cobalt-infused glass pigment previously thought to have been invented a century later. Although some conservators argue this discovery merely indicates later restoration efforts, the smalt particles are embedded beneath intact, original varnish layers rather than sitting atop them. Consequently, scholars must revise the long-standing timeline of inorganic pigment synthesis in Europe, recognizing that fifteenth-century artisans engaged in sophisticated chemical experimentation far earlier than historical documentation suggests.
Which of the following best expresses the main conclusion of the passage?
- Historians must revise the accepted chronological timeline of European pigment synthesis to account for early fifteenth-century chemical experimentation.Answer
- BSpectroscopic micro-analysis demonstrates that Renaissance patrons had far less influence over artistic material choices than previously believed.
- CThe detection of smalt in mid-fifteenth-century Tuscan chapels is primarily an artifact of subsequent conservation and restoration projects.
- DSmalt particles in Tuscan chapel frescoes are situated directly beneath intact, original varnish layers rather than on top of them.
- EFifteenth-century Tuscan artisans completely abandoned expensive imported pigments such as lapis lazuli in favor of cobalt-infused glass compounds.
