« The Society of Painters in Tempera was founded in 1901 by Lady Herringham and by a group of painters whom a study of the Book of Cennino Cennini had inspired to a quest for better craftsmanship.
The declared Object of the Society was « Improvement in the art of Tempera painting by the interchange of the knowledge and experience of the members. » (John D. Batten 1925) In 1997 The Society of Tempera Painters was established following the decline of the original Society. »
