A portable sundial which, when closed, looks like a leather bound book (bought in a sort of arts and crafts market in Plaza Santa Ana in Madrid at about one in the morning after an enjoyable meal in a nearby restaurant 🙂 )
This is the sundial over the door of Dial Cottage home of the railway pioneer George Stephenson.
The inscription reads-
George Stephenson. Engineer. Inventor of the Locomotive Engine. Lived in this cottage from 1805 to 1823; his first locomotive (Blücher) was built at the adjacent colliery wagon shops, and on July 25th 1814 was placed on the wagonway which crosses the road at the east end of this cottage.
And the Big Daddy of all sundials, the Samrat Yantra, part of the observatory of Jantar Mantar in Jaipoor, India.
