The Intriguing Case of the Braunschweig 1334 Sundial

This article investigates two medieval German sundials from 1334 and 1346 that were early attempts to display equal-length hours. The 1334 dial had a horizontal style, which was a failure, while the 1346 dial used a style pointing to the celestial pole, making it the earliest known sundial of its kind.

A Sundial for a School in Southern Sweden

This article details the design and construction of a sundial for the Elias Fries School in Hyltebruk, Sweden. The sundial, made from a large stone cut in half, features a polar-axis aligned shadow pin and a dial plate raised 20 degrees from the ground. It is designed to be an artistic and educational tool demonstrating the sun's daily and seasonal movements without indicating precise clock time.
