Final answer:
Edwin Arlington Robinson is best known for both "Miniver Cheevy" and "Richard Cory," which are poems that explore themes of disillusionment and the disparity between appearance and reality.
Step-by-step explanation:
Edwin Arlington Robinson is most known for both "Miniver Cheevy" and "Richard Cory". These two poems are among his most famous works. "Richard Cory", published in 1897, is a narrative poem that describes a man who appears to have everything anyone could want — wealth, education, charm, and respect.
Despite this, he ultimately takes his own life, stunning those who only saw his outward success. "Miniver Cheevy" is another poem that delves into the life of its title character, who disdains the modern world and longs for a more heroic age. Both poems are known for their exploration of the themes of disillusionment and the disparity between appearance and reality.
