«Pompeo Ugonio's Historia delle stationi di Roma, published in 1588 and dedicated to Camilla Peretti, was the presage to a much larger work that would consume Ugonio up to his death in 1614. The Theatrum urbis Romae, a compendium of notes so vast in scope that it never saw publication, survives in two voluminous manuscripts (Cod. Vat. Barb. Lat. 1994, and Ms. I, 161, Biblioteca Ariostea, Ferrara). In a series of diagrammatic maps, Ugonio attempted to trace a continuum in the evolution of Rome from its origins through its transformation into a Christian capital, culminating in his own time with the master plan envisioned and partly realized by Sixtus V.»
