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.
