Edwin Austin Abbey was an American muralist, illustrator, and painter. He flourished at the beginning of what is now referred to as the "golden age" of illustration, and is best known for his drawings and paintings of Shakespearean and Victorian subjects, as well as for his painting of Edward VII's coronation. His most famous set of murals, The Quest and Achievement of the Holy Grail, adorns the Boston Public Library.

The Holy Grail is a treasure that serves as an important motif in Arthurian literature. Various traditions describe the Holy Grail as a cup, dish, or stone with miraculous healing powers, sometimes providing eternal youth or sustenance in infinite abundance, often guarded in the custody of the Fisher King and located in the hidden Grail castle. By analogy, any elusive object or goal of great significance may be perceived as a "holy grail" by those seeking such.
