The Analemmatic Sundial SourceBook was first published in 2004, revised in 2014, and now is again available in digital form on CD or by download from the north American Sundial Society. What is it? It is a very comphrehensive reference to the origins, history, and modern evolution of the analemmatic sundial compiled and edited by Fred Sawyer III, President of NASS.
It started with J.L de Vaulezard publishing a small work of 15 pages in 1640 descibing the dial in vague terms, promising to reveal its construction later "if I see that the work has been well received by you...." Four years later de Vaulezard published his "Treatis of the origin, demonstration, construction and usage of the analemmatic dial". A decade later Samuel Foster published "Elliptical or Azimuthal Horologiography" further describing the analemmatic sundial. The SourceBook reprints a facsimile of this and three other of Foster's original works.
The Historical Period includes not only the works of de Vaulezard and Foster but works by Aubri, Tuttell, Richer, Parent, Bion, Lalande, Bedos de Celle, Lambert, Oberreit, Boutereau, Meikle, Perret, Peaucellier, Viala, Lisbonne, Gruey, Marchand, Roguet and Chomard. For over 250 years these authors provide the earliest proof of the analemmatic dial, the introduction of the Foster/Lambert, diametral, and Parent variations, as well as many important historical and theoretical discussions of the analemmatic dial and its properties.
Study of the analemmatic sundial had a revival at the turn of the 20th century and again beginning in 1986 with the publication of "Equator Projection Sundials" by de Rijk. Other articles include R.J. Vinck's "Times of Sunrise and Sunset on the Analemmatic Sundial" further descriptions of seasonal points by Bailey and Sonderegger. Vinck's "The Elliptical, Circular and Linear Dials" detailing of the mathematical foundation of a whole class of azimuthal sundials with examples of strange looking sundials by Sawyer, Olgesby, Gianni, Massé, Sassenburg, Sonderegger, and Rouxel.
Fred Sawyer III has a number of articles within the Analemmatic SourceBook, including "Of Analemmas, Mean Time and the Analemmatic Sundial", "Foster's Diametrical Sundial", and many more.
