Herculaneum is one of the classics of Rochesterian literature, so appreciated by a wide audience, spiritualist or not. With his peculiar style, Rochester chooses as his setting the glorious Roman Empire, at the time of his incarnation as Cáius Lucilius, in the first century of the Christian era, masterfully describing the landscapes and customs of the inhabitants of the ancient city of Herculaneum, which, together with Pompeii, is destroyed by Vesuvius in 79 AD. In a captivating narrative, he recounts the bonds of sympathy and animosity that unite him with relatives, friends, and companions of old journeys, who for several lifetimes walk together in search of spiritual progress. And the great surprise: we will have the pleasure of knowing the spiritual trajectory of Allan Kardec - present in this work through the venerable Father John - and his encounter with the beloved master Jesus. To have access to this brilliant historical work is, in addition to traveling through time accompanying Rochester on his journey, to enjoy valuable lessons on the true importance of love and forgiveness.
