A historical philosophical work by Chrysippus, the third head of the Stoic school. While the original text is lost to time, its contents are preserved through fragments and references by later authors like Galen and Marcus Aurelius. It is considered by some scholars to be the first formal treatise on psychotherapy. The book detailed the Stoic approach to treating the 'passions' or emotional disturbances through logic and cognitive restructuring. It laid the foundational framework for what would eventually become modern Cognitive Behavioral Therapy (CBT).
There's a lost book by Chrisipus, the third head of the Stoic school called the lo the lost therapeuticon, right? Like the Necronomicon or something.

"Donald Robertson identifies this as the 'first ever book on psychotherapy' during a discussion about the historical roots of emotional regulation and Stoicism. It is mentioned to highlight that the 'cognitive' approach to emotions is thousands of years old."
