The Casino di Villa Boncompagni Ludovisi is a villa in Porta Pinciana, Rome, Italy. Measuring 2.200 square meters, it is all that remains of a country retreat, best known as Villa Ludovisi, established in the 16th century by Cardinal Francesco Maria Del Monte. The Cardinal was a diplomat, intellectual, art connoisseur, collector, and protector and patron of such very different figures as Galileo and Caravaggio. The ceiling of the casino has the only fresco ever done by Caravaggio, Jupiter, Neptune and Pluto, which reflects, in symbolic imagery derived from Classical mythology, another of the cardinal's interests, alchemy. The casino is also known as the Casino dell'Aurora, after an important fresco by Guercino.
