Richard Melville, also known as Melvill, a prolific dial maker who worked in Ireland and Scotland, was known for his Welsh slate dials. A number have survived, but few as complex as this, the "Salisbury Dial". Various forms of these multi-gnomon horizontal dials were sold, being square, rectangular, round or octagonal. Like most of Melville's dials, this example bears no date, but the Crystal Palace Co. was formed in 1852 to move the Crystal Palace to Sydenham in 1854, and Clifton notes that Melville was working in Liverpool in 1856, in London in 1858, and in Dublin from 1864-71, indicating that this dial was made between 1856 and 1864.
