How does Truth Unveiled by Time (Bernini) elucidate its Provenance?
Bernini began the preparatory work for Truth Unveiled by Time in 1645, during the critical period after the death of his main patron pope Urban VIII, and the figure of Truth was largely complete by 1652. Despite never completing the figure of Time, Bernini left the sculpture in his will in perpetuity to the first-born of the Bernini family; although in fact Bernini tried to sell the work to Cardinal Mazarin of France. It remained in the family (displayed on a tilted stucco block during the 19th century) until 1924, when it was purchased by the Italian government and transferred to its current home on a plinth in room VI of the Galleria Borghese. Its plinth there was originally tilted but it is now on a flat plinth after a recent restoration, leaving Truth more upright as it was originally displayed.
Sometime in 1647 Bernini designed and began executing the larger-than-life-size marble group. The sculpture was referred to in a letter sent by the duke of Bracciano, Paolo Giordano II Orsini to Cardinal Mazzarino on July 6, 1647.   After his death the sculpture was situated in Bernini’s home on Via della Mercede until 1852. Per Bernini's last will and testament, the statue was to remain in perpetual custody of his family, “because by seeing it, all my descendants will be reminded that truth is the most beautiful virtue in the world inasmuch as it is eventually revealed by time.” Subsequently the sculpture was placed in Palazzo Bernini on Via del Corso until 1924. After 1924, the sculpture was held in storage at the Galleria Borghese until it was acquired in 1958 by the Italian government.
