The Trojan War occurred before the Dark Age of Ancient Greece, during the Mycenaean Era if it occurred at all. The story of the Trojan War is known primarily through the writing of the Greek bard Homer, author of the Iliad and Odyssey.
Classical Age of Ancient Greece
The Classical Age of Greece begins with the Persian War (490-479 B.C.) and ends with the death of Alexander the Great (323 B.C.). Besides war and conquest, in this period the Greeks produced great literature, poetry, philosophy, drama, and art.
During the Archaic Age (c. 776-480 B.C.), the city-states known as poleis (polis in the singular) started developing. The citizen father of a family would farm a small plot of land and would otherwise be engaged in the life of the polis. It was during the Archaic Age that philosophy started and the poet Sappho of Lesbos wrote.
