The Scaphe Sundial at Hever Castle, Kent

This article details the author’s investigation into the enigmatic scaphe dial at Hever Castle, often called the "Roman" sundial. It discusses its historical background, previous examinations by Ward and Vaughan, and the author's measurements and analysis, concluding it is likely an unworkable dial despite its ancient appearance.

Ivory Sundials of Nuremberg Incorporating a Scaphe Sundial

This article analyses the scaphe sundial component found in Nuremberg ivory diptych sundials. It uses vectorial representation and measured photographic distances to determine the intended latitude for three examples, concluding that Reinmann and Miller's scaphes were likely designed for 49° latitude, and Lesel's for 48°, primarily for Nuremberg.

The Dial from the ‘Palais Farnèse’: Roman or Modern?

This article investigates a spherical sundial in the 'Palais Farnèse', Rome, questioning its Roman origin due to its perfect state of conservation and lack of gnomon hole. It hypothesises the dial is an 18th or 19th-century copy of a Roman original, potentially with a symbolic rather than functional purpose related to the palace's 'Trophées Farnèse' compositions about Time.

The Sundials of Gerald Laing

This article highlights the sundial works of pop artist Gerald Laing, known for at least four large sculptural pieces. These include two Scottish obelisk sundials, a 37ft market cross in Inverness, and "Axis Mundi" in Edinburgh, often featuring complex gnomonics and graphical representations of the Equation of Time.

Isle of Wight Sundial Mystery Solved

This article solves the mystery of a sundial pedestal at Farringford, Alfred, Lord Tennyson's home. It was designed by Mary Seton Watts, wife of the painter G.F. Watts, likely as a memorial for Tennyson and his wife Emily. The pedestal features carvings related to Tennyson's poem The Sundial and a motto.

Mass Dials - Where Did It All End?

This article explores the indistinct end of mass dials, discussing "transitional" forms that bridge medieval and scientific dials. It notes the appearance of numerals (Roman, Hindu-Arabic, or dot form) around the circumference of later mass dials, indicating a shift towards 12 o'clock noon, and touches on conversions to scientific dials.

Dialling Manuscript Found

The discovery of a previously unknown early Italian manuscript (1477-1505) at Lund University, Sweden, is announced. Predating works by Oronce Finé and Nicholaus Kratzer, this anonymous manuscript contains significant sections on astronomy, mathematics, and sundials, featuring various dial types, including a horizontal scaphe sundial.

The Scaphe of Carthage

This article describes a rare eyelet-hole scaphe sundial discovered at a Roman villa in Carthage, dating to 1st century AD or later. It details the marble artefact's exterior, including oak-leaf decoration and a fixing wedge, and its highly polished interior with seven non-concentric curves and eleven hour lines. Unique inscriptions in Greek and Latin Julian month names, including 'Augustus' (dating it after 9 BC), and zodiac signs mark its exceptional nature.

Lieut. Commander Richard (Dick) Andrewes DSC.R.N.

This tribute remembers Lieut. Commander Richard "Dick" Andrewes, a BSS member known for his wartime naval service, mathematical degree, and enthusiasm for dialling. He designed a unique dial for his home and an analemmatic dial for a conservation centre. He is particularly remembered for delineating a scaphe dial at the Horniman Museum, ingeniously overcoming its organic shape by using a marble to find the bowl's lowest point.

Old Sundials on the Territory of Former Socialist Federal Republic of Yugoslavia

This article surveys 214 fixed sundials in the former SFR Yugoslavia, now divided into multiple new states. It highlights a Roman spherical dial from Sremska Mitrovica, the oldest Serbian sundial at Studenica Monastery (12th century), and the horizontal dial at Belgrade Observatory. It notes the scarcity of sundials in Macedonia and Bosnia and Herzegovina due to Turkish reign, and discusses Italian-influenced medieval stone dials on the Croatian Adriatic coast, including one in Dubrovnik with both contemporary and old Italian hour scales.

The Turnbull Dial

This article describes the Turnbull Dial at Corpus Christi College, Oxford, a 26-foot pillar featuring a total of 27 dials. Designed in 1579-1583 by Charles Turnbull, it includes a principal south-facing dial, a perpetual calendar, tables for planetary years and lunar months, and moon-time corrections. The dials use the old unequal hour system, and the pillar has undergone several restorations.
