the eruption and again the following year but no work was done on recovery. Soon after the city's burial, survivors and possibly thieves came to salvage valuables, including the marble statues from the Forum and other precious materials from buildings. There is wide evidence of post-eruption disturbance, including holes made through walls. The city was not completely buried, and the tops of larger buildings would have been visible above the ash, making it obvious where to dig or salvage building material. The robbers left traces of their passage, as in a house where modern archaeologists found a wall graffito saying "house dug". Over the following centuries, its name and location were forgotten, though it still appeared on the Tabula Peutingeriana of the 4th century. Further eruptions, particularly in 471–473 and 512, covered the remains more deeply. The area became known as the La Civita (the city) due to the features in the ground. The next known date that any part was unearthed was in 1592, when architect Domenico Fontana, while digging an underground aqueduct to the mills of Torre Annunziata, ran into ancient walls covered with paintings and inscriptions. His aqueduct passed through and underneath a large part of the city and would have had to pass through many buildings and foundations, as they still can be seen in many places today. However, he kept the finding secret. In 1689, Francesco Picchetti saw a wall inscription mentioning decurio Pompeiis ("town councillor of Pompeii"), but he associated it with a villa of Pompey. Francesco Bianchini pointed out the true meaning, and he was supported by Giuseppe Macrini, who in 1693 excavated some walls and wrote that Pompeii lay beneath La Civita. Herculaneum itself was rediscovered in 1738 by workers digging for the foundations of a summer palace for the King of Naples, Charles of Bourbon. Due to the spectacular quality of the finds, the Spanish military engineer Roque Joaquín de Alcubierre made excavations to find further remains at the site of Pompeii in 1748, even if the city was not identified. Charles of Bourbon took great interest in the finds, even after leaving to become king of Spain because the display of antiquities reinforced Naples' political and cultural prestige. On 20 August 1763, an inscription [...] Rei Publicae Pompeianorum [...] was found and the city was identified as Pompeii. Karl Weber directed the first scientific excavations. He was followed in 1764
