Demosthenes was a statesman and orator who lived in Athens during the fourth century BC. To overcome a speech impediment he is said to have practised speaking with pebbles in his mouth. He also gave speeches on the seashore, projecting his voice over the sound of the waves in preparation for tumultuous crowds. Delacroix depicts him barefoot on a beach with one arm outstretched towards the water.
