Two complete lines and the top of a third written in a right-sloping cursive. It is noteworthy that the cross-bar of t does not continue to the right of the hasta. Since there are traces of address script on the back, this must come from the top of the right-hand column of a letter.
quidquid itaque potuero
ad uos ui.[..]dos festinabi-
. . . . . . . . . . . .
uid[en]dos is likely; after this one expects festinabo, but the last letter is clearly i; therefore presumably festinabi-/[mus.
