Homer (; Ancient Greek: Ὅμηρος [hómɛːros], Hómēros; born c. 8th century BC) was a Greek poet who is credited as the author of the Iliad and the Odyssey, two epic poems that are foundational works of ancient Greek literature. Homer is considered one of the most revered and influential authors in history.Homer's Iliad centers on a quarrel between King Agamemnon and the warrior Achilles during the last year of the Trojan War. The Odyssey chronicles the ten-year journey of Odysseus, king of Ithaca, back to his home after the fall of Troy. The poems are in Homeric Greek, also known as Epic Greek, a literary language which shows a mixture of features of the Ionic and Aeolic dialects from different centuries; the predominant influence is Eastern Ionic. Most researchers believe that the poems were originally transmitted orally. Despite being predominantly known for its tragic and serious themes, the Homeric poems also contains instances of comedy and laughter.Homer's epic poems shaped aspects of ancient Greek culture and education, fostering ideals of heroism, glory, and honor. To Plato, Homer was simply the one who "has taught Greece" (τὴν Ἑλλάδα πεπαίδευκεν, tēn Helláda pepaídeuken).
