The image of the lamb contrasts with the fierceness of the tiger.
Explanation:
The lamb is an archetype in literature because this animal has long been associated with the idea of innocence and purity. This is also the role that the lamb plays in this poem. When Blake introduces the tiger, he emphasizes its fierceness and wonders who could have create such an animal. He then wonders if the same mind could have also created the lamb. The implication is that the lamb is completely different to the tiger in the fact that it is sweet and innocent as opposed to fierce.
The answer is: The image of the lamb contrasts with the fierceness of the tiger.
In the poem "The Tyger," the author William Blake makes reference to the lamb because he wonders how the same God who created such a benevolent creature could also conceive a dangerous and ferocious animal like a tiger.
In "The Tell-Tale Heart," the narrator claims to have killed the old man because he hated the appearance of the man's eye. However, his murderous actions are actually a reflection of his madness. The reasoning behind the narrator's crime undermines his argument that he is sane and proves his mental instability.
