Note 29 — BOOK I.

There were similar remains in the choir, the design of which I have seen. They were covered over in 1733. Among other curiosities was the portrait of the patriarch Popone, of the Emperor Conrad, and his son Henry; the design, action, and characters, like the mosaics at Rome; executed about the year 1030. See Bartoli, Antichità di Aquileja, p. 369; and Altan, Del vario Stato, &c. p. 5.
