In Greek and Roman mythology, Aeneas was a high-born Trojan warrior who survived the fall of Troy, safely exiting the city with his family and possessions. Throughout the ages, writers interpreted the character of Aeneas from different perspectives. In the 13th century, Guido delle Colonne, an Italian judge and author, wrote a narrative of the Trojan war suggesting that Aeneas betrayed Troy to the Greeks in exchange for safe passage from the city. Thise idea is reflected in the beginning of “Sir Gawain and the Green Knight.”

The Queen of Heaven and her child are allusions to the Virgin Mary and Jesus Christ; in context, “courteous” means gracious and kind.

“Zephyrus” is an allusion to the Greek god of the west wind. The ancient Greeks also considered Zephyrus one of the gods of spring, since winter ended with the arrival of gentle winds from the west.
The interjection alluding to St. Giles is unclear. It could refer to St. Giles the Abbot, a 6th-century monk, or to St. Giles of Assisi, a follower of St. Francis of Assisi in the 13th century. The allusion most likely refers to St. Giles of Assisi, who was especially known for his austerity and whom St. Francis called his “Knight of the Round Table.”
