Victoire Baltard, a French Architect on a grant at the French Academy in Rome, partially confirmed and revised that reconstruction, and, as required by his grant, made a new reconstruction of the theater in 1837.
Basing his work on Vitruvius, on fragments of the Forma Urbis,
the early third century C.E. marble plan of Rome, and on the earlier
study of Canina, Baltard also undertook two excavations in the Largo
dei Librari and the Piazza dei Satiri that clarified the extent and
architectural character of the Theater. The first cleared part
of the facade; the second uncovered the east apse of the scaenae
frons and confirmed its plan on the Forma Urbis. First published in
the early 20th century, his drawings have served as the model for
all subsequent reconstructions of the Theater.

During the three decades after Baltard, finds from the Theater of Pompey were, with one exception, largely unrecorded, but, in 1865, there was a second large-scale excavation. While Pietro Righetti, then owner of Palazzo Pio, was excavating the foundations for a new wing in the NE court, his laborers, working at a depth of 7.14 m, found, parallel to the north facade of the court, part of the south exterior wall of the Temple of Venus Victrix. Of peperino blocks, it consisted of the lower section of an arcade decorated with engaged half-columns.
Adjacent to the wall lay the remains of a street, a fine marble
pavement of porta santa and cipollino, and the gilt thumb from
a colossal bronze statue.
The Hercules Righetti as discovered in 1865
Directed by Architect Luigi Gabet, Righetti's workers made further
major discoveries. Excitedly increasing the size of their excavation,
Gabet and his workmen laid bare the rest of the statue, a colossal
Hercules (known today as the "Hercules Righetti"). It lay on its
back partially submerged under an ancient shelter of travertine
slabs at the SE corner of the foundations of the Temple of Venus
Victrix. The excavators raised it, and Righetti later sold it
to Pope Pius IX, who subsequently transferred it to the Sala Rotonda
in the Vatican Museums where it stands today.
