Create a unique Greek Orthodox Icon inspired by the character of Bilbo Baggins from J.R.R. Tolkien's "The Hobbit." Depict Bilbo as a saintly figure, adorned with a Byzantine halo and dressed in traditional Greek Orthodox robes. Incorporate iconic elements from the story, such as the One Ring, Sting (Bilbo's sword), and the contract for the journey to the Lonely Mountain, to symbolize his adventures and spiritual journey. The artwork should be rendered in the characteristic flat and stylized manner of Greek Orthodox Icons, using gold leaf and vibrant colors. The composition should emphasize Bilbo's central role in the narrative, surrounded by intricate patterns and decorative elements that reflect the rich visual language of the Byzantine artistic tradition.
