| Abstract: | The Roman wreck found off Grado, not far from the city of Aquileia in the north Adriatic Sea, was recovered in 1999. The ship carried various kinds of amphoras with processed fish. A lead pipe, inserted in the hull near the keel, is curious evidence which the authors try to explain. The pipe could be connected to a piston‐pump to suck water. A theoretical reconstruction demonstrates how this apparatus could work and that it could be used to feed a tank to allow trading in live fish over a long distance. © 2011 The Authors |
