Alexander is played by Charlie Merriman, an actor who studied Ancient Greek and Latin at Cambridge University. With Barefaced Greek, he performs in plays and videos in Ancient Greek. The speech is taken from the 'Anabasis of Alexander' (Book VII Chapter X), written around 130 AD by the Roman/Greek historian Arrian. Arrian had access to eyewitness accounts which are now lost (principally Ptolemy and Nearchus), and modern historians generally agree that this speech was a real historical event, and that Arrian gives a good representation of its likely content. Ultimately, however, this speech was written by Arrian, and Alexander's exact words are not known.
