The words architect and architecture, derived from Greek through Latin, remind us that the architectural profession has its origins in the ancient world. Architects in a sense have always existed, in that wherever there have been buildings there has been someone to design them, but architecture has not always been a profession. It was so in antiquity, as it is today, but was not always in the intervening period. There were no doubt working masons in Greece and Rome who could put up a modest building on their own, and we know of at least one amateur architect, the Emperor Hadrian, but in general the designing of buildings was a matter for the professional man.
