See the sundial and color swatches of Perseverance in Stereo3D, like if you were on board the #rover. Just let your eyes' line of sight be parallel (not cross-eyed) with left eye in front of left image and right eye in front of right image.
A face-like Lectern style sundial in the garden of Greenbank House near Glasgow. This may be an original 16th century sundial, or it may be a later replica of an earlier design. Lectern sundials are one of the three types of ancient Scottish sundials. They can also be found in some parts of continental Europe, particularly the Netherlands, which was a major trading partner of Scotland at the time.
The Collins Street Sundial in the Townhead area of Glasgow. It may seen surprising, but Scotland had amongst the highest number of sundials in the 17th and 18th centuries. This includes obelisk sundials which were unique to Scotland. Like this newer one, many had multiple gnomons, the official name for the bit which casts the shadow onto the dial.
Love this sundial which I came across on my recent trip to Culzean Castle to the southwest of Glasgow. Not only is the quality of the sculpture great, but the lichens and mosses which have colonised it over time just add a completely new layer to its appearance.
I don’t suppose anyone here knows anything about sundial geometry? I have a plate with no gnomon and no idea where to start? #sundial#geometry#HelpPlease
