Salvi wanted to place the statue of Agrippa and the statue of the Virgin where the statues of Abudance and Heatlh are now. It was Pannini that changed the plan.

The four allegorical statues located on the attic were carved by Agostino Corsini, Bernardino Ludovisi, Francesco Queirolo and Bartolomeo Pincellotti. They represent the good effects of rain on Earth fertility and the four major produces that depend on water supply.

The first statue on the left holds the horn of plenty and is symbol of the Abundance of fruits. The second one is holding ears of wheat and represents Fertility of Crops. The third one is holding a cup and bunches of grapes symbolising the Products of Autumn. The last on portraits the Joy of Prairies and Gardens and is all adorned with flowers.

The reliefs of Agrippa that commands the contruction of the acqueduct and the Virgin that indicates the soldiers the location of the source of water are by Andrea Bergondi and Gian Battista Grossi.

The inscription on the attic says: CLEMENS XII PONT. MAX. AQUAM VIRGINEM COPIA ET SALUBRITATE COMMENDATAM CULTO MAGNIFICO ORNAVIT ANNO DOMINI MDCCXXXV PONT VI. Translation: Clemens XII Pontifex Maximus decorated the Virgin Acqueduct and committed it with abundance and salubrity to the magnific cult in the Year of the Lord 1735, 6th year of his pontificat.

The inscription just below says: PERFECIT BENEDICTUS XIV PONT. MAX. Translation: Benedict XIV Pontifex Maximus made perfect.

The other inscription behind the statues of Abundance, Health and Ocean says: POSITIS SIGNIS ET ANAGLIPHIS TABULIS IUSSU CLEMENTIS XIII PONT. MAX. OPUS CUM OMNI CULTU ABSOLUTUM A. D. MDCCLXII. Translation: The statues and the reliefs were decreed to be placed here by Clemens XIII Pontifex Maximus and the work was solved from every further work and care in the Year of the Lord 1762.

The decorations of the fountain also feature around 30 species of plants located where the environment is more suitable to them. continues...
