Scottish sundials of the renaissance period are not just more numerous than in any other country, they are also stylistically unique. This is particularly notable when the size and wealth of Scotland at the time are taken into account. They are free standing stone sculptures of the 17th and 18th centuries with many small dials inscribed on them. Accurate timetelling is clearly not the aim. Precision is sacrificed for decorative effective. Unlike the sundials of similar date on the continent where baroque decoration may be added, the mathematical complexity of the Scottish dials is decoration enough. The ancient sundials of Scotland can be grouped into three main styles: lectern, obelisk and facet-head.
