Santuario di Rossano di Vaglio

In woodland at Rossano, near Vaglio Basilicata, stand the remains of the great sanctuary where the Lucanian communities gathered around the goddess Mephitis. Its paved plaza, altar and fountains, in use from the fourth century BC to the first century AD, make it one of the defining monuments of pre-Roman Basilicata.

Why it matters

The sanctuary at Rossano is interpreted as a federal cult place: a religious centre shared by the Lucanian communities rather than the possession of a single town. Founded around the middle of the fourth century BC beside a spring, at a junction of communication routes, it served as the setting where a scattered mountain people expressed common identity — and, in its later centuries, the stage on which the absorption of the Lucanians into the Roman world can be read directly in the archaeology.

Its deity, Mephitis, belonged to the Italic pantheon and was linked with waters and vapours, an attribute the site honours in stone: semicircular fountains and a drainage channel still trace the management of the sacred spring. The inscriptions recovered here, in Oscan, Greek and Latin, are counted among the most important testimonies to Lucanian civilisation, documenting a sanctuary where languages coexisted as power changed hands.

What to notice

The core of the monument is a paved sacred plaza of sandstone slabs, about twenty-one by thirty-seven metres, with a two-section altar podium at its centre — the ritual heart of the complex. The architecture forms three sides of enclosure: rooms and porticoes on columns and pilasters wrapped the square, with the entrance on the north-west flanked by two semicircular fountains that fed a drainage channel carrying water from the spring through the sacred area.

The sanctuary honoured Mephitis alongside Iuppiter, Domina Iovia and Mamerte. Its inscriptions and successive building phases reflect the transition from Lucanian independence to Roman rule; the complex was renovated in the second century BC and remained in use into the first century AD.

Context and history

Italian scholarship places the sanctuary's origin around the mid-fourth century BC, at the moment the Lucanian confederation needed shared religious institutions to bind its communities. The choice of site was deliberate: dense woodland near a spring, away from settlements, at the meeting point of routes through the upper Basento territory. Over some four centuries the complex grew from a cult place into a monumental sanctuary, its plaza and porticoes built and rebuilt as Lucanian society first flourished and then came under Roman dominion. Its abandonment in the first century AD closed the pre-Roman chapter of the valley.
