Re: Re: Any Wall Sundials On Irish Buildings
And here is another on a slightly larger scale:
The paving of St Peter’s Square
The paving is varied by radiating lines in travertine, to relieve what might otherwise be a sea of cobblestones. In 1817 circular stones were set to mark the tip of the obelisk’s shadow at noon as the sun entered each of the signs of the zodiac, making the obelisk a gigantic sundial’s gnomon. Above is a view of St. Peter’s Square from the cupola which was taken in June, 2007.
