Truth Unveiled by Time is a marble sculpture by Italian artist Gian Lorenzo Bernini, one of the foremost sculptors of the Italian Baroque. Executed between 1645 and 1652, Bernini intended to show Truth allegorically as a naked young woman being unveiled by a figure of Time above her, but the figure of Time was never executed.

Upon his election to the papacy in 1623, Maffeo Vincenzo Barberini took the name Pope Urban VIII and appointed Bernini as the principal artist for the papal court in Rome. According to Bernini's biographer Baldinucci, Maffeo had 'scarcely ascended the sacred throne' when he summoned Bernini and told him:

"It is your great fortune to see Cardinal Maffeo Barberini Pope, but our fortune is far greater in that Cavalier Bernini lives during our pontificate."

Bernini enjoyed great success during his time as the principal artist for the papal court but, after Urban's death in 1644, he was removed by the incoming pope, Innocent X. The new pope had more conservative tastes and favored Bernini's rival Algardi. Despite the fall from favor this did not stop Bernini from occasionally working for the new pope - One of his most famous works, the Fountain of the Four Rivers, was one of the projects done for Innocent. He still maintained his position as the architect of St. Peter's despite his removal from the papal court and, after Innocent's death in 1655, was immediately given two major commissions at St. Peter's: decorating the Cathedra Petri and building a colonnade round the piazza.

Bernini's rationale for creating Truth Unveiled by Time was, according to his son Domenico, as a sculptural retort to attacks from opponents criticizing his failed project to build two towers onto the front of St. Peter's Basilica. While this is certainly plausible, historians are unsure of the validity of Domenico's claims relating to his father's reasoning. Cracks had appeared in the facade due to the inability of the foundations to support the towers and Bernini's architectural expansion received the blame. What many fail to mention is that most of the blame lies with Carlo Maderno, the previous architect who built weak foundations for the monumental task being requested, and Pope Urban VIII, who kept pressuring Bernini for heavier, more elaborate bell towers.

During the difficult time after Urban's death, Bernini was able to find peace and serenity in his overwhelming confidence that one day he would be vindicated. So strong was this conviction that he created Truth Unveiled by Time to express this confidence in his eventual vindication. Despite this conviction, the sculpture of Father Time was never begun and the project remained incomplete. It has been suggested by historian Franco Mormando that Bernini's return to public favor after Innocent's death might have made the sculptural piece lose the emotional urgency it had previously possessed, which would make sense considering he had been reinstated to his previous place in the upper echelons of society.

Truth Unveiled by Time is a white marble sculpture that is 280 cm in height, which includes the 17 cm pedestal it rests upon. Seated on a boulder with dramatic, flowing drapes behind her, the maiden Truth holds a representation of the Sun in her right hand at shoulder level as she rests her left leg on the Earth. She gazes upward beyond the Sun with a look of peace and comfort, perhaps even joy. Truth has already been stripped of her garments. The strategically placed drapery of the statue is suggestive and not as blatant as truly profane scenes. Her bare chest and stomach are visible while her groin is covered by some of the flowing drapery. There is a sense of movement, emotion, and vigor in her being, and the cold marble appears to be as supple as real flesh. According to Bernini's biographer Baldinucci:

"His chisel was applied in such a way that one could believe it had been cutting wax instead of marble."
