Bridge of boats across the Tiber.
'As all great events in Nature have their heralding signs, so is the approaching visit of the King announced to you even by the concourse of wayfarers to your City. We, however, have to order you to clothe the waves of Tiber with a bridge [of boats]. The boat, thus used, is no longer moved by slowly hauled ropes, as it is wont to be. Fixed itself, it affords a means of transit to others. The joining of its planks gives the desired appearance of solidity; all the terror of the waves is removed by its likeness to the land, and the traveller passing over it unharmed only wishes that the bridge were longer.
'Let a safe bulwark of lattice-work shield the bridge on the right side and on the left. See that you give no cause for misadventure of any kind. You have a noble opportunity of distinguishing yourself in the presence of so many Senators and of the King himself, the rewarder of every well-done work. On the other hand, if you do it badly and put him out of humour, woe be unto you!
'We send A B, a servant of our Praefecture[861], to assist you and your staff and bring us report of the accomplishment of the work; for so heavy is our responsibility in this matter that we dare not leave anything to chance.'
[The King whose advent to Rome is here announced may be Witigis, after his election in the plains of Regeta (August, 536). But the fact that he is apparently approaching Rome by the northern bank of the Tiber, coupled with the directions in the preceding letter for the repair of the Flaminian Way, makes it more probable that some visit of Theodahad (probably in the year 535), when he would come from Ravenna to Rome, is here in prospect.]
