Margaret Gatty (1809-1873) was an English writer best known for her researches on sundials and British seaweeds. After marrying the Rev. Alfred Gatty in 1839, she moved to Ecclesfield, Yorkshire, where she pursued her literary and scientific studies. This volume, first published in 1872, contains detailed descriptions of various styles of sundials, many taken from Gatty's own collection. Over 350 sundials from across Britain and Europe are described, and each sundial's location is noted in this work, which was one of the first popular books on the subject. Examples included range from portable sundials to early Saxon sundials, as well as the more familiar church sundials. This volume is one of Gatty's best known works, and remains a valuable reference for the various types of sundials and the variations and similarities in their mottoes.
