Other collections
In the Southern loggia of Palazzo Altemps there are four reliefs from the Albani del Drago Collection, which have been known and sketched since the 15th century and subsequently made famous by the studies by Winckelmann. These became the property of the Italian State in 1964, after an attempt was made to export them illegally. Another very famous series reproduced in numerous drawings and etchings since the moment it was unearthed at the beginning of the 18th century is the cycle of frescos in the Pallavicini-Rospigliosi Collection, donated to the National Roman Museum in 1923 and now on display on the first floor of the palazzo. Works originally in private ownership also include the statue of the Crouching Venus (from the Jandolo Collection) and the Maenad statue (from the Veneziani Collection), a piece transferred to State ownership as payment for inheritance taxes.
