Anyway, the Romans used concrete. The Parthenon in Rome has the largest unsupported concrete dome roof in the world made 2 millennia ago, we can barely get a concrete building to last a few decades. The Roman Oyster Shuckers are so old the blades have been replaced 4 time and the handles three. ![]() Anyway I did not say when 'earlier' they were made. ![]() |
