Ceramists 16th century
Francesco Xanto Avelli was an Italian ceramicist. He is best known for his painted maiolica works.
Xanto's signed works all date from between 1530 and 1542. Each bears his name and the date of the piece; many also were given ambitious tags explaining their meanings. The surviving pieces appear to be similar in nature, with the exception of the signatures, to most other maiolica ware produced in Urbino at the time. Xanto signed his works with a number of different variants of his own name; besides those with his full name, pieces signed fra Xanto in his hand are known to exist.
Besides being a ceramicist, Xanto was also a poet; in the 1530s he wrote a sequence of sonnets in praise of Francesco Maria I della Rovere, then duke of Urbino. An elegant fair copy survives in the Vatican Library.
Bernard Palissy was a French natural scientist, painter, ceramicist and sculptor, geologist and writer of the French Renaissance.
Born into a family of artisans, Palissy apprenticed with his father as a glass artist and traveled throughout southwestern France comprehending pottery and studying geology. Today he is best known for his amazing lead-glazed pottery with images of various animals and people. After seeing a white glazed cup, probably of Chinese porcelain, in the 1540s, he set out to learn the secrets of its manufacture. His early research is described in De l'art de la terre. Although Palissy never succeeded in reproducing what he saw, his experiments gave him a thorough knowledge of the chemical compositions of minerals.
From 1575 in Paris, Palissy gave public lectures on natural history, which were published as Discours admirables (1580). In this treatise, Bernard Palissy touches on an incredibly wide range of subjects, from the techniques of ceramics, metallurgy and chemistry to hydrology, geology and fossils. He correctly identified fossils as the remains of ancient life. This work reveals him as a writer and scientist, a creator of modern agronomy and a pioneer of the experimental method, with scientific views generally more advanced than those of his contemporaries.
