Subiaco in the Abruzzi was the cradle of the Benedictines, and in that neighbourhood St Benedict established twelve monasteries.
In Italy, Spain, Portugal and Brazil only a few monasteries survive the various revolutions, and in a crippled state; but signs are not wanting of renewed life: St Benedict's own monasteries of Subiaco and Monte Cassino are relatively flourishing.
He went to the mountainous districts of the Abruzzi, and at last came to the ruins of Nero's palace and the artificial lake at Subiaco, 40 m.
Driven from Subiaco by the jealousy and molestations of a neighbouring priest, but leaving behind him communities in his twelve monasteries, he himself, accompanied by a small band of disciples, journeyed south until he came to Cassino, a town halfway between Rome and Naples.
At Subiaco and at Rome they had produced in 1465-1471 the earliest editions of Cicero, De Oratore and the Letters, and eight other Latin authors.
They are traversed by three principal valleys: (I) that of the Anio, now called Teverone, which descends from above Subiaco to Tivoli, where it enters the plain of the Campagna; (2) that of the Trerus (Sacco), which has its source below Palestrina (Praeneste), and flows through a comparatively broad valley that separates the main mass of the Apennines from the Volscian mountains or Monti Lepini, till it joins the Liris below Ceprano; (3) that of the Liris (Garigliano), which enters the confines of New Latium about 20 m.
Hither St Benedict migrated from Subiaco in the early years of the 6th century, and established the monastery that became the metropolis of Western monachism.
