The Fontana del Tritone built in the 17th century by Gian Lorenzo Bernini seen at night. The passage from Ovid's Metamorphoses that inspired Bernini to make this fountain was:
Already Triton, at his call, appears
Above the waves; a Tyrian robe he wears;
And in his hand a crooked trumpet bears.
The sovereign bids him peaceful sounds inspire,
And give the waves the signal to retire.
His writhen shell he takes; whose narrow vent
Grows by degrees into a large extent,
Then gives it breath; the blast with doubling sound,
Runs the wide circuit of the world around:
The sun first heard it, in his early east,
And met the rattling ecchos in the west.
The waters, list'ning to the trumpet's roar,
Obey the summons, and forsake the shore.
