Moondials and the Moon

Explores principles and types of moondials, including tabular, volvelle, graphical and adjustable designs. Analyses moon’s orbital motion, parallax, illumination, and visual limitations under moonlight. Proposes improvements to enhance accuracy towards that of simple sundials, and presents prototype experimental dials demonstrating refined timekeeping performance.

Equatorial Equinoctial Sundial

Details construction of a combined equatorial and equinoctial sundial using stacked car engine starter rings, cylindrical and brass components. Describes adjustable latitude setting and a novel gearing mechanism employing concentric eccentric spindles to apply the equation of time correction on two knobs, enabling mean time readings without manual calculation.

A Flagpole Sundial

Presents design of a vertical sundial adapted for flagpole installation, with dial furniture indicating sunrise and sunset signal times for hoisting and lowering the flag. Covers dial plate calibration for specific latitude, readability challenges under low contrast, and suggests precision improvements via vernier scales and solar-aligned sighting mechanisms.

The Courtyard of Time of Cascina Picchetta, Cameri, Piedmont

Examines the sundial ensemble in the courtyard of Cascina Picchetta, a 17th-century Italian villa. Analyses six wall-mounted sundials across two façades with varying hour systems (Italian, Babylonian, French, temporary), equatorial orientations, declination corrections, and historical decorative motifs. Explores Jesuit influences and conservation considerations.

Further Comments on the Sundial of St. Mary’s Stoke D’Abernon, Surrey

Reassesses the original Anglo-Saxon sundial at St Mary’s, Stoke D’Abernon through newly discovered early photographs. Reveals the dial’s inclined face, previously unrecognized, and reviews past interpretations. Discusses typological features of Saxon angled-gnomon dials, date uncertainty, and implications for correct dating and classification.
