A newly discovered medieval scratch dial in the Armenian Church in Jerusalem is detailed. Discovered on the southern wall, it's a half-circle with 12 hour sectors marked by Armenian letters. A simpler "twin sundial" is also present, possibly for different religious needs. Historical evidence suggests the dials date to the 12th century, making them the first post-Byzantine sundials found in Israel.

A report on the well-attended BSS conference in York. Topics included Leicester"s Millennium Time Trail, the discovery of early wooden dials in Ipswich, Samuel Foster's graphical dialling techniques, and the restoration of astrolabes and sundials at Oxford's Museum of the History of Science. Tours of local sundials, an auction, and discussions on unusual dials and polar dial design were also featured.

This second part details using stereographic projection for graphical design of declining and reclining vertical, and double horizontal sundials. It explains how to determine sub-style angles and style heights, and how the projection can cover full 24-hour periods. The article also covers William Oughtred"s "Horizontal Instrument" and Blagrave"s "Mathematical Jewel" as related applications.

Originally published in "The Countryman" in 1948, this article describes a highly accurate horizontal sundial built by the author while interned in a Japanese camp in China. Constructed from scrap materials using improvised tools and limited references, this unique dial provided correct clock time with built-in Equation of Time correction, serving as the camp's only reliable timepiece.

This article discusses an inexpensive armillary sundial widely advertised as "Classic Art For Your Garden" but designed for Latitude 38° N. It explains how to modify such a dial for correct use in the UK (approx. 52° N) by tilting its main body or by physically removing and reattaching elements, enabling it to indicate local solar time.

This article presents the design for a horizontal sundial usable anywhere in the UK to show GMT, requiring only a slight tilt adjustment for specific latitudes. It employs a gnomon rod mounted at a 53-degree angle and concentric circles on the dial plate represent different longitudes. A formula for calculating hour lines is provided.
