According to legend, on January 7, the anniversary of the death of

Pope Innocent X, or on full moon nights, the ghost of Donna Olimpia appears near Palazzo Pamphilj in her carriage filled with gold and drawn by four horses, leaving a trail of fire that rages through the streets of Rome...



The fountain in the middle of Piazza Navona,

for which the Pimpaccia (oops...actually the Pope)

commissioned Gianlorenzo Bernini in 1647,

is dedicated to the 4 rivers.

These giant river gods represent the great waterways of the 4 continents (Oceania had not yet been discovered)

One of them has his head covered with a veil because its source was not yet known at the time.

Can you tell me which river it is?
