"With his abbacy, the quantity of our [historical] evidence dramatically increases [and d]evelopments in secular politics can now be seen to impinge on Farfa's land acquisitions.
"[1] Fulcoald's abbacy can therefore be defined in terms of three objectives that are apparent in the surviving sources: (a) to extend its landholdings and secure its rights to its properties, (b) to promote a strict and disciplined monastic observance, and (c) to "steer as untroubled a course as possible through the choppy waters of Italian politics".
[1] To this end Fulcoald sought and received a privilege of Duke Lupo prohibiting women from certain grounds in the vicinity of the abbey.
The king granted one estate—"two large tracts of upland pasture"—to Farfa, an estate later disputed with the dukes of Spoleto.
The anonymous Libellus constructionis Farfensis gives his length of abbacy as nineteen years, which coupled with Gregory's catalogue of abbots, which begins Fulcoald's tenure in 740, suggests a date of 759 for his successor.
