Elgin sent his crew of artists to Athens, to make drawings and casts of the famous antiquities. By now the Ottomans had converted the Parthenon into a mosque, treating it with respect and care. Furthermore, the Ottomans were using the Acropolis as a military fort. For this reason, Lusieri had to bribe the officers to permit them entrance.
With the outbreak of war in Egypt between the Ottomans and the French, led by Napoleon, the artist's only means of access to the Acropolis was with a written document of authorization from the Sultan, known as a Firman. During this time, England had joined forces with the Ottomans to defeat Napoleon in Egypt, reversing it back to an Ottoman territory. This event had a decisive and positive effect on the relationship between the Ottoman authorities and Lord Elgin as the British ambassador.
