"What scenes superb, displayed on every side!
What native dignity and rural pride!
Slow from the bay exalted Merion swells,
And the luxuriant Richmond far excels;
Art's rich embroidery glistens o'er her plains,
Simple and great, here various nature reigns."

- From "Phoenix Park", a poem by John Leslie, published in London, 1772. Original in [NLI] LO 5221.
The poem is a general celebration of the vista of Dublin.
He is comparing Mount Merrion favourably to the Fitzwilliams' English seat at Richmond.
