  1. Key idea 1

    Florence welcomes a mysterious young count

    At a reception at the Pitti Palace, the young German count Wilhelm enters a world where attention itself becomes a puzzle. He plays chess with Lord Seymour while the guests wonder why Prince Forsiani and the papal nuncio take such an interest in him. Even his welcome seems to carry a hidden history.

    Behind the polite talk stands another mystery: a woman who is not there. Hints about her beauty and influence make her absence more powerful than anyone else's presence. Florence introduces itself through smiles, gossip, and things left unsaid.

Who it’s for

Readers who love gothic atmosphere, secret palaces, hidden power, and a mysterious heroine. It suits anyone drawn to old Florence, occult lore, and nineteenth-century French fiction that asks large questions about belief and the will.

What this book is

Isis is the opening part of a series of philosophical novels by Auguste de Villiers de L'Isle-Adam, dedicated in Paris in July 1862. The author calls Isis the x in an equation, the great unknown, and says the whole work will define itself once it is complete. This first part, called Tullia Fabriana, sets the stage in Florence in 1788.

You meet a young German count, Wilhelm, who arrives in Italy full of hope, and a marquise whom the whole city admires and no one understands. Around them stand an old prince with hard-won advice, a palace full of hidden mechanisms, and a woman whose mind seems to hold a secret plan. The book mixes court gossip, occult study, and meditations on faith and doubt in a modern age. Let us begin with the evening that starts it all.

Key point 1 of 9

A stranger is noticed in Florence

The story opens at a reception at the Pitti Palace. The Duchess of Esperia presents Count Strally-d'Anthas, a young traveler just come from Germany, to all of Florence. He looks no more than eighteen or twenty, and he plays chess with Lord Seymour while others dance.

The guests whisper. Prince Forsiani, an old courtier about to leave as ambassador to Sicily, seems unusually interested in the boy. The papal nuncio is introduced to him by the duke himself, and the gossips wonder why. One lady suggests the prince once knew the young man's mother well.

Later two fragments of talk hint at a hidden woman. The nuncio speaks of an ally of great caliber who was not at the palace, and says he may leave her a note. Forsiani tells the duchess he has seen this beautiful woman who never shows herself, and that she accepted his arm to her carriage.

The chapter sets the tone of the whole book. Everyone smiles, everyone hints, and the most important person is the one who is absent.
