No doubt the four ladies representing science, the arts, poetry and industry and the mermaids on the Ross Fountain will emerge from beneath their frozen covering when the weather soon warms up.    The fountain was made in France for the Great Exhibition of 1862 then bought by gunmaker Daniel Ross in 1862 for £2,000, who gifted it to the city of Edinburgh and it was installed in Princes Street Gardens in 1872.  It was refurbished in 2018 with many of the 122 parts being recast and painted.  The fountain’s pump runs continually recycling and cleaning the water and unlike most fountains, it is not turned off in winter.
