To start, the building on the left is very architecturally proportional and there is a tetra style. The west work of the building is highly ornamented seen with the capitals of the columns, also we can predict this building is from the Baroque era as we see ovate windows on the west work. To contrast, the sculpture on the left is more lively and less uniform. The man appears to be throwing a stone. I believe this statue is done by Bernini, an architect and sculptor of the Baroque period. Both works represent grandeur, common for the era.
