SUNDIAL

The oblong dial is located high up on the south side of the Basilica. Its modern design contrasts notably with its setting. I can imagine some debate over modern versus traditional styles. It was installed in 2020; a caption refers to renovation.

The dial’s height and size makes it very visible. John Renner, who took these photos, suggests convincingly that there must always have been a dial of some sort there, I’d have thought, to be visible to the friars from their cloister and help them say their hours on time. I have now managed to locate a photo taken from the cloister of an earlier dial with a much simpler day-marker. Probably it replaced an even earlier one.

The details of the new dial include 4 signs of the Zodiac; 2 midday roman numerals; 1/2 hours marked with pale arrowed lines; and a fairly traditional motto. The most interesting feature is the gnomon, which is tilted for accuracy and looks adjustable. As the photos clearly show, the sun’s rays are focused through a small hole onto the dial face – here, at exactly 9.30 am.
