Location and History:

Saepinum, located in modern-day Altilia near Sepino in the province of Campobasso (Italy), represents one of the best-preserved examples of a small Roman provincial town with its theater being a notable architectural feature. The ancient city sits approximately 15 kilometers south of modern Campobasso in the south-central region of Italy (Princeton Encyclopedia).

Brief History of City

Originally a Samnite settlement dating to the 4th century BCE, Saepinum was strategically positioned on the ancient road connecting Beneventum to Corfinium. The original settlement was located on the mountain above the later Roman town, with remnants of its Cyclopean masonry walls still visible today (Stillwell et al.). The Romans captured Saepinum in 293 BCE during their campaigns against the Samnites (Stillwell et al.).

The city walls of the Roman municipium were constructed during the reign of Tiberius, between 2 BCE and 4 CE, as confirmed by inscriptions (Stillwell et al.). The urban layout followed the typical Roman orthogonal plan with a forum at the center and major buildings including temples to Jupiter and Apollo. By the 4th century CE, the presence of tombs within the city walls suggests significant abandonment. Following the collapse of the Western Roman Empire, Saepinum was captured by Saracens in 882 CE (Wikipedia).

Brief History of Theatre

The theater of ancient Saepinum was constructed during the Julio-Claudian period in the first decades of the 1st century CE (Teatri Greci e Romani 1995). It was strategically positioned close to the city walls in an area somewhat removed from the urban center to minimize disruption to city life during both construction and subsequent performances (“Parco Archeologico”). The structure underwent renovations in the mid-4th century CE, particularly to the scaenae and porticus (Teatri Greci e Romani 1995). From the 18th century onwards, rural buildings were constructed over parts of the theater, repurposing materials from the ancient structure. Recent restoration work has preserved these later additions for their historical value, transforming them into museum spaces (“Parco Archeologico”).

Current Status

Preservation Condition

The theater of Saepinum is relatively well-preserved compared to many ancient structures of its kind. The orchestra, ima cavea, and three tiers of steps of the media cavea remain in good condition (Teatri Greci e Romani 1995). The rural buildings constructed over the scaena and summa cavea from the 18th century onwards have been integrated into the archaeological site, now serving as museums and offices (Teatri Greci e Romani 1995).

Conservation Efforts

The Sepino Archaeological Park manages the preservation and presentation of the theater as part of the larger ancient city complex. The park is described as “a place out of time, in which the past coexists in close contact with the present” (“Parco Archeologico”). The integration of later historical periods into the presentation of the site represents a holistic approach to conservation, acknowledging the continuous inhabitation and use of the space through different eras.

 

Renovations / Excavations

Ancient Renovations

  • Chronological phases:
    • Initial construction: Julio-Claudian period (early 1st century CE)
    • Significant alterations to scene building in 4th century CE (Sear 154)
    • Restructuring of the scaena and the porticus around the mid-4th century CE (Teatri Greci e Romani 1995)

Architectural Modifications

The 4th-century renovations appear to have focused on the scaena and porticus areas, though specific details of these modifications are not extensively documented in the available sources. The continued use of the theater into the 4th century is notable, as it corresponds with a period when parts of the city were being abandoned, as evidenced by tombs appearing within the city walls during this period (Stillwell et al.).

Excavation Campaigns: Archaeological investigation of Saepinum has been conducted through several major campaigns, though comprehensive documentation of all excavations specific to the theater remains limited in the available sources.

  • 1950s: Excavations led by Valerio Cianfarani, Soprintendenza alle Antichità degli Abruzzi e del Molise (Cianfarani)
  • Late 1970s: Studies by Mario Gaggiotti, Università di Perugia, focusing particularly on the theater (Gaggiotti 59-67)
  • Early 1980s: Documentation work by Matteini Chiari, resulting in the publication “Saepinum: Museo documentario dell’Altilia” (Matteini Chiari 143-56)
  • Recent decades: Ongoing conservation efforts by the Soprintendenza Archeologia, Belle Arti e Paesaggio del Molise

Modern Restorations: Recent restoration work has preserved the 18th-century rural buildings constructed over parts of the theater, integrating them into the archaeological site as museum spaces (“Parco Archeologico”). These restorations have maintained the historical continuity of the site while making the ancient structures accessible to visitors.

Publication History

The archaeological research at Saepinum’s theater has been documented in several key publications by scholars, including Cianfarani (1958), Gaggiotti (1979), and Matteini Chiari (1982), establishing a foundation for our understanding of the site’s archaeological significance and architectural features. These works have been supplemented by more recent studies that continue to expand our knowledge of this important Roman provincial theater.
