Fairy dream and Hercules allegory
Herr Spinell compares the life of Kloterjahns to that of a fairy dream and Hercules. Frau Kloterjahn is a fairy dream, a wonderful creature that got pulled away from her safe and beautiful nest by a brawny Hercules who is in his mind Herr Kloterjahn. The beautiful sylph doesn't make a life of her own but blindly holds Hercules's arm and follows him with pride. He touches on the women's role as only wives to their husbands and that being their only identification shown even in the tradition of a wife taking her husband's last name instead of her own, at which Herr Spinell looks with disgust.
Golden crown symbol
When Frau Kloterjahn told Herr Spinell about her life before her marriage he imagines her wearing an invisible golden crown. That crown disappeared when Herr Kloterjahn took her away from her garden. Golden crown symbolizes the life Frau Kloterjahn left behind, her life, to be Herr Kloterjahn's wife.
Spinell-name symbolism
Spinell is a precious metal which is very rare. It could symbolize the rareness of Herr Spinell's character and him being a rare "conscious" person on the world, it could represent the rareness of his artistic mind.
Einfried symbolism
The name Einfried looks to be derived from a word "einfriedung," which translates to fence. Einfried could be seen as a fence to the outside world where patients are safely guarded from its troubles. The narrator even describes Herr Spinell's reason for staying there as "stealing time from God-Almighty".
