Alessandro Specchi's 1694 engraving illustrates part of the complex process of moving and re-erecting the ancient Egyptian obelisk that now stands before St. Peter's Basilica in Rome. The obelisk was moved there in 1586 by Pope Sixtus V from a location about 275 yards away, under the supervision of architect Domenico Fontana (1543-1607). The massive project took 13 months. The monument still stands in St. Peter's Square today, over 400 years later.
This engraving was published as a large folding plate in Book III of Templum Vaticanum et ipsius origo by Carlo Fontana (1634-1714), one of eight prints depicting the moving of the obelisk. In 1590 Domenico Fontana had published a book documenting his engineering feat, Della Trasportatione dell'Obelisco Vaticano e delle fabriche di Sisto V [On the Transportation of the Vatican Obelisk and the Buildings of Sixtus V], illustrated with engravings by engravings of Natale Bonifacio. Specchi based his plates for Templum Vaticanum on Bonifacio's. An example from the 1590 book on the web site of the Linda Hall Library indicates the kinds of adaptations Specchi made in combining this source material into his own splendid large compositions (see References below). The scaffold depicted by Bonifacio is faithfully reproduced in Specchi's version, but Specchi has omitted the background that obscures the structural elements at the bottom of the scaffold, changed the arrangement of horses and workers, and of course, combined several different phases of the process into one giant plate. Integrated into the illustrations are text panels in Italian, explaining the process shown in the pictures. The text refers to the obelisk as La Guglia – the Spire – as it was known colloquially in Rome at the time.
The obelisk was quarried in Egypt during the age of the pharaohs in the 13th century BCE, and stood in Alexandria. There it had fallen and been re-erected by the Romans during the reign of Augustus. In 37 AD, the Roman Emperor Caligula transported it by an enormous barge to Rome where it was set up in the center of his chariot racecourse. By the 1500s, nobody knew how these earlier civilizations had managed to erect these enormous monuments, and at 83 feet high and weighing 330 tons, the risk of having it fall and shatter during the process of maneuvering it into place made Fontana's feat a daring one. Using massive 51-foot levers, 40 winches and huge teams of men and horses to power the operation, his plan was a triumphant success, and encouraged Sixtus to unearth and restore other Egyptian obelisks brought to Rome by the ancient emperors that had long since fallen.
Alessandro Specchi was an Italian architect, urban planner, engraver and aquatintist. A student of the architect Carlo Fontana, he assisted in the construction of Fontana's chapel of St. Fabian and San Sebastiano Fuori le Mura in Rome. Specchi was a prolific architectural engraver from at least 1684, known especially for his prints of Roman palaces and other buildings. He engraved 79 plates for Fontana's major work Templum Vaticanum et ipsius origo (1694) and contributed 52 plates to Quarto Libro del Nuovo Teatro di Palazzi di Roma (1699) and 286 plates for Studio d'Architettura Civile (1702-21), both documenting Rome's architecture and issued by the renowned de'Rossi publishing house.
