Original prompt & settings (JSON) ↗The Lombards held Sutri for exactly 140 days by the papal biographer's count — and handed it back stripped of all its resources.
140 days, then a return
The near-contemporary papal biography of Gregory II in the Liber Pontificalis says Lombards seized the fortress of Sutri by deceit and possessed it for 140 days; the standard year is 728.
Gregory II sent repeated letters and admonitions to King Liutprand, and supplied many gifts.
The source says the fortress had been stripped of its resources before the king restored and donated it to the apostles Peter and Paul.
Two verbs pulling different ways
The wording restituit atque donavit — restored and donated — is legally ambiguous. Some historians treat Sutri as an important step toward papal territorial power; others stress that it was a restoration of property already belonging to the Patrimonium Sancti Petri.
There is no treaty text behind it. The surviving evidence is a narrative in the Liber Pontificalis.
That passage names the fortress of Sutri specifically, and does not extend to Vetralla or a collection of unnamed Latian towns.
What 728 did not include
The primary account describes no treaty signed at Sutri and no meeting there between pope and king. Its account of Gregory personally meeting Liutprand near Rome belongs to a different campaign involving the dukes of Spoleto and Benevento.
Liutprand had not occupied all of the Exarchate of Ravenna. Treccani places a later capture of Ravenna under his nephew Hildeprand in the 730s, followed by a Byzantine recovery.
The Prosopography of the Byzantine Empire renders the occupation as 727/728 from the indiction evidence; no exact modern calendar day is supplied.

Traditional date. This date is the conventional one, not one fixed by a contemporary record.
What the sources leave uncertain
- The standard year is 728, while the Prosopography of the Byzantine Empire renders the occupation as 727/728 from the indiction evidence; no exact modern calendar day is supplied.
- The wording restituit atque donavit—“restored and donated”—is legally ambiguous. Some historians treat Sutri as an important step toward papal territorial power; others emphasize that it was a restoration of property already belonging to the Patrimonium Sancti Petri.
- The extent of the transfer is uncertain in later retellings. The near-contemporary passage specifically names the fortress of Sutri, so this sheet does not add Vetralla or a collection of unspecified Latian towns.
