Adeodatus Pope, 672–676

Vltalian dying towards the end of January 672, was succeeded (April 11) by the Roman Adeodatus, son of Jovinian, whose four years' pontificate is devoid of importance in the history of the city. To this Pope is, however, due the restoration of the celebrated monastery of S. Erasmus on the Cœlian, of which in former days he had been a member. Founded in the sixth century, in the house of the Valerii, this monastery was later united with the Abbey of Subiaco, but fell to decay at some date unknown. Its ruins, however, with the remains of some ancient paintings, endured beside S. Stefano until near the end of the sixteenth century.

Donus, 676–678

Donus or Domnus, son of the Roman Mauricius, succeeded Adeodatus on November 2, 676, but reigned little more than a year. The Liber Pontificalis informs us that he paved the Atrium of S. Peter's with great blocks of white marble, and, as it is scarcely probable that the quarries provided the required supply of costly material, we may infer that it was furnished by the despoiled monuments.
