Teresa, Contessa Guiccioli

Teresa, Contessa Guiccioli (1800–1873) was the married lover of Lord Byron while he was living in Ravenna, Italy, and writing the first five cantos of Don Juan. She wrote the biographical account Lord Byron's Life in Italy.
On 19 January 1818, Teresa married Count Guiccioli. It was three days later, on 22 January, that she met Lord Byron at the home of Countess Albrizzi.
Alexandre Dumas included her as a minor character in his novel The Count of Monte Cristo using the disguised name "Countess G-". Lord Byron also used this shortened name in his journals.
