Lord Byron was a British Romantic poet and satirist whose poetry and personality captured the imagination of Europe. Although made famous by the autobiographical poem Childe Harold's Pilgrimage (1812–18)—and his many love affairs—he is perhaps better known today for the satiric realism of Don Juan (1819–24).

He travelled extensively across Europe, especially in Italy, where he lived for seven years in the cities of Venice, Ravenna, and Pisa. During his stay in Italy he frequently visited his friend and fellow poet Percy Bysshe Shelley. Later in life Byron joined the Greek War of Independence fighting the Ottoman Empire and died leading a campaign during that war, for which Greeks revere him as a folk hero. He died in 1824 at the age of 36 from a fever contracted after the First and Second Siege of Missolonghi.

It is also known that Lord Byron had inscribed his name on the columns of the Temple of Poseidon in Sounion.

The inscribed name possibly dates from his first visit to Greece, on his Grand Tour of Europe before he acquired fame. Byron spent several months in 1810–11 in Athens, including two documented visits to Sounion. There is, however, no direct evidence that the inscription was made by Byron himself. Byron mentions Sounion in his poem Isles of Greece:

"Place me on Sunium's marbled steep,
Where nothing, save the waves and I,
May hear our mutual murmurs sweep..."

While graffiti is unacceptable on any public monument , Byron did pay for weapons for the Greek Revolution and would eventually "die for Greece".
