ng which the
imperial gifts no doubt ranked). His architectural works in Istria were
considerable; and in Ravenna he consecrated the two churches of S.
Vitale and S. Apollinare in Classe, built by Julian, the treasurer. In
Istria he founded the monastery of S. Andrea, near Rovigno, and the
church of S. Maria Formosa, or "in Canneto," at Pola (which had property
in the exarchate of Ravenna), a magnificent church, which has been
spoken of in the chapter on Pola. The "feud" consisted of a palace, with
its dependencies, and three towers in the city of Pola, and a quantity
of land in the district. The wood at Vistro where the treasure was found
was also given to S. Apollinare by Maximian. In 1001 Otho II. gave S.
Maria and S. Andrea to the archbishop of Ravenna; afterwards they
belonged to S. Mark's, Venice. A document of 1138 in Ravenna shows Abbot
Paul, of the monastery of Pomposa, asking for himself and his successors
for one hundred years the renting of certain lands from Martin, abbot of
S. Maria in Canneto and of S. Andrea. In 1200 the feud consisted of many
rights of jurisdiction, tithes, and charges, both in the city of Pola,
and in towns in its territory, some of the land having been sold, with
Urban III.'s permission, between 1185 and 1187. There was a chapel of S.
Apollinare and a house with their belongings near the Porta del Duomo,
and three towers, the country possessions being spread over eleven
places. At this time Engelbert III., Count of Goerz, stole it, and held
it for some time, notwithstanding an appeal to the Popes Celestine III.
and Innocent III. In 1213 the archbishop granted the feud to a certain
Stefano Segnor, so he must have then regained it. Seven years later
Simeon, archbishop of Ravenna, conceded his lands in Istria to Guido
Michele and his successors, with the obligation to renew the contract
every sixty years, and reserving the right of appeals. The Castropola
bought the feud from the Giroldi about 1300 for 1,800 "lire piccioli."

Aquileia was the most prosperous city of the empire after Rome, having
600,000 inhabitants in the days of its prosperity. The fleet which kept
the capital in communication with the eastern coast of the Adriatic, and
so with Liburnia, Giapidia, Pannonia, and the Levant, had a station
there. Trajan took the division which was called Aquileian or Venetian
from the Pretorian fleet at Ravenna. It had charge of the Upper Adriatic
from Ancona to Zara, and of the shore from
