How is the poem "The Tyger" romantic? (Not love but in the romanticism era.)

Blake's work often falls into its own category; he was a philosopher, a spiritualist, a visionary. His work, however, is clearly romantic in the tradition of Romanticism as it developed in Europe and then in the United States. "The Tyger" reflects Romanticism in its basic subject and content. Blake raises and explores a primary spiritual question: the very nature of God. Romantics turned away from conventional thinking, rejected the conventional teachings of the Church and State, and focused instead on the individual and his relationship to the universe around him. In "The Tyger," Blake does not define God according to Church doctrine, but instead examines and questions the nature and the mystery of God. The poem also emphasizes beauty, although it is a fearsome kind of beauty. "The Tyger," then, is an example of Romanticism for its elements of spirituality, mystery, and beauty.
