The plaque through which the spring water flows marks the entry to the garden of the stream that feeds all the ponds. The inscription reads
HIC GELIDI FONTES
here are cool springs
HIC MOLLIA PRATA
here soft meadows
The quotation is from Virgil’s tenth Eclogue, and may be understood to describe the blessings of art as well as nature.
Caithness stone, John R. Nash, 1992
