Gregory’s Meridian, St Andrews
Posted in Curiosities, Fife, History at 12:00 on 13 December 2014
I was in St Andrews at the back end of September and spotted this on the pavement in south South Street. I don’t think I’d noticed it before. Is it relatively new?
It is Gregory’s Meridian line.
A plaque on the wall gives more information.
James Gregory looks to have been one of the 17th century’s greatest scientists. A meridian, Calculus, the diffraction grating and a type of telescope?

I spent 4 years at St Andrews studying Mediaeval History. The Department’s building was in South Street. To my great shame, this escaped me.

Phew! Just tried to find out more and discovered that the memorial was put in place 30 years after I left St Andrews.

Thanks, Elizabeth.
So it is recent then?

It is indeed relatively new. It has only been there for a few months. The University of St Andrews published a press release about it.

Remi,
Thanks for looking in and commenting.
The Mean Time difference seems about right. I’ll certainly take your word for it.
