Final answer:
Vittorio Spinazzola's archaeological work in Pompeii advanced the understanding of Roman urban life, fresco techniques, and commercial practices due to his innovative horizontal excavation technique, particularly on the Via dell'Abbondanza.
Step-by-step explanation:
Vittorio Spinazzola's discoveries significantly contributed to our understanding of daily life in Pompeii and Herculaneum. Spinazzola was an Italian archaeologist who conducted excavations in Pompeii in the early 20th century, employing a method of uncovering artifacts in a more careful and detailed way. Rather than digging vertically, he excavated horizontally, methodically uncovering streets and buildings layer by layer. This technique allowed for the discovery of artifacts in situ, showing where and how people lived at the time of the eruption.
Spinazzola's work revealed various aspects of Roman urban life, including the layout of homes and shops, street life, and the social dynamics of urban spaces. He uncovered and studied the intricate frescoes and decorations on the walls of Pompeian buildings, which contributed to a better understanding of Roman art and aesthetics.
One of Spinazzola's most significant contributions was his work on the Via dell'Abbondanza, the main street of Pompeii, providing insights into the commercial life of the city. This work also brought to light the importance of advertising in Roman culture, as evidenced by electoral graffiti and commercial signs discovered on the exteriors of buildings. His approach to excavation laid the groundwork for modern archaeological practices in Pompeii and set a new standard for the preservation of ancient sites.
