Letters documenting their relationship and Claire's struggle to keep a connection with her daughter Allegra. A precious window into Byron in private.
Exchanges revealing the friendship and tensions between the two women, as well as the circulation of ideas within the circle.
For decades the keeper of unpublished letters and manuscripts, she became a figure sought after by collectors — the inspiration for Henry James's novella “The Aspern Papers.”
Anecdotes
In the summer of 1816, Claire Clairmont stayed with Mary and Percy Shelley near Lake Geneva, very close to the Villa Diodati rented by Lord Byron. It was during those rainy evenings, when the group challenged one another to write ghost stories, that Mary Shelley conceived *Frankenstein*.
It was Claire who, first among the circle, wrote to Lord Byron to meet him, and not the other way around. From this affair a daughter, **Allegra**, was born in **1817**; Byron agreed to acknowledge her but refused to let her be raised by her mother.
Byron placed little Allegra in a convent near Ravenna, despite Claire's desperate protests. The child died there of fever in **1822**, at only five years old — a loss that haunted Claire for the rest of her life.
To earn a living, Claire worked for years as a governess and tutor, notably in Russia in Moscow, far from the romantic turmoil of her youth. She was fluent in several languages.
Having lived to the age of 80, Claire outlived nearly the entire Romantic circle. Toward the end of her life in Florence, admirers sought to buy from her the letters of Shelley and Byron that she had kept — a situation that inspired Henry James's novella *The Aspern Papers*.

Daily Life
Morning
In her youth within the Shelley circle, Claire would rise to read, study languages and write in her journal. Mornings were devoted to reading and to her writing work.
Afternoon
Afternoons were spent on walks, shared readings and lively literary discussions with Mary, Percy and their friends. Later in life, as a governess, she gave lessons to the children in her care.
Evening
The Romantic evenings were filled with music, conversation and sometimes invented tales, as during the famous Swiss summer. They would read aloud and debate poetry and philosophy.
Food
Influenced by Percy Shelley, an advocate of a vegetarian diet, the circle favoured bread, vegetables, fruit and milk, and was wary of meat and alcohol. Meals were often simple and frugal.
Clothing
Claire wore the high-waisted Empire-style dresses in light muslin, with shawls and bonnets in keeping with early 19th-century fashion. Her attire remained that of a cultivated young woman of the middle class.
Housing
Her life was marked by instability: lodgings rented as her travels through Switzerland and Italy required, governess's rooms in Russia, then apartments in Florence. She never owned a true home of her own.
