Comment: Abstract. The erection of two obelisks at Rome before 10 B.C. must be considered in connection with the erection of two obelisks at Alexandria 13-12 B.C. The comparison of all activities around these events indicates, that a close co-operation of Romans and Egyptians took place from 15 B.C. onward. Before the first obelisk transport to Rome, Roman engineers and shipbuilders had the opportunity to study the Egyptian transport technology on the Nile. Based on these experiences, the Roman navy was capable of constructing an appropriate ship for the transport of obelisks across the Mediterranean. Until now it was believed, that heavy, granite objects were laid on top of ships at the stone quarries near Aswan and then brought northward. This assumption can no longer be upheld. Instead columns and obelisks were transported hanging in water between the two hulls of a double-ship. The loading of a double-ship was easy and without using any power. The Roman obelisk-ship was composed of three interconnected ships. Two ships supported the obelisk, which hung between them in the water, and the third ship was centred between their bows. The ship in front provided the streamlined water flow necessary at open sea, and also the propulsion. Of all Roman ship types the trireme appears best suited to be adapted to this role as an integral part of the obelisk-ship. As the result of this investigation every detail contained in reports of Pliny, Suetonius and Ammianus corresponds to the construction of the hypothetical Roman obelisk-ship. Definite clues about the Roman double-ship technology give remarks on the sinking of Caligula's obelisk-ship in the Portus near Ostia. A part of the former western mole, which consists of pozzolana concrete has to be interpreted as a platform built up on pillars above the obelisk-ship.
