Sabratha apparently had a large enough maritime trade to warrant a permanent office at Rome's port of Ostia. This mosaic, from the Piazzale delle Corporazioni at Ostia, is what remains of Sabratha's office. The commercial and civic symbol of the elephant was also used by Lepcis Magna. It is not impossible that the coastal towns of Tripolitania exported elephants (along with other wild beasts) and ivory on a large scale.
