To avoid getting caught by the manager of the insulae, Zhang Heng and Dadatis left through the window they came in.
Dadatis had prepared a small boat on the Tiber River downstairs.
As Zhang Heng climbed into the boat, he noticed no oars on board, so he asked the old Persian, "How are we supposed to get out of here?"
"Relax, we just have to go down the river," replied the old trainer as he undid the moorings.
The boat then began to drift downstream under the influence of the current.
Zhang Heng and Dadatis each occupied one end of the boat, one at the bow and the other at the stern.
