Heh... the Romans really liked those, and boosted a bunch. That one in particular was brought over for Caligula, and the boat that had to be built to transport it was so large, even by Roman standards, that it became a tourist attraction in its own right. Eventually, Claudius had it sunk end-down for use as a form to pour the concrete mole to anchor the breakwater for his all-season port.
Thanks for adding to the history!
