Twelve Egyptian obelisks are scattered throughout Rome. The smallest one towers atop a most strange base: a carved elephant.
Diocletian,the Roman emperor from 284 to 305, brought the Egyptian obelisk to Rome. It was rediscovered in the 17th century, or Pope Alexander VII commissioned its erection.
The base was designed by the famous architect Gian Lorenzo Bernini. The elephant is meant to represent wisdom,as in some cultures, the animals are associated with the trait. Bernini also chose an elephant because it’s large enough to support the column’s weight.
There was a preliminary dispute between the Dominican Father Paglia and Bernini about the pedestal’s design. The cleric proposed one surrounded by four dogs, and one in each corner,to honor the Order of the Dominicans, to which he belonged.
Its believed Bernini’s assistant Ercole Ferrata is the one who actually sculpted the pachyderm. The ensemble was finally erected in February 1667 in the Piazza della Minerva in front of the church of Santa Maria Sopra Minerva, and where it stands nowadays.
