We know very little about the author of The Odyssey and its companion tale, The Iliad. Most scholars agree that Homer was Greek; those who try to identify his origin on the basis of dialect forms in the poems tend to choose as his homeland either Smyrna, now the Turkish city known as Izmir, or Chios, an island in the eastern Aegean Sea. According to legend, Homer was blind, though scholarly evidence can neither confirm nor contradict the point.

The ongoing debate about who Homer was, when he lived, and even if he wrote The Odyssey and The Iliad is known as the "Homeric question." Classicists do agree that these tales of the fall of the city of Troy (Ilium) in the Trojan War (The Iliad) and the aftermath of that ten-year battle (The Odyssey) coincide with the ending of the Mycenaean period around 1200 BCE (a date that corresponds with the end of the Bronze Age throughout the Eastern Mediterranean). The Mycenaeans were a society of warriors and traders; beginning around 1600 BCE, they became a major power in the Mediterranean. Brilliant potters and architects, they also developed a system of writing known as Linear B, based on a syllabary, writing in which each symbol stands for a syllable.

Scholars disagree on when Homer lived or when he might have written The Odyssey. Some have placed Homer in the late-Mycenaean period, which means he would have written about the Trojan War as recent history. Close study of the texts, however, reveals aspects of political, material, religious, and military life of the Bronze Age and of the so-called Dark Age, as the period of domination by the less-advanced Dorian invaders who usurped the Mycenaeans is known. But how, other scholars argue, could Homer have created works of such magnitude in the Dark Age, when there was no system of writing? Herodotus, the ancient Greek historian, placed Homer sometime around the ninth century BCE, at the beginning of the Archaic period, in which the Greeks adopted a system of writing from the Phoenicians and widely colonized the Mediterranean. And modern scholarship shows that the most recent details in the poems are datable to the period between 750 and 700 BCE.

No one, however, disputes the fact that The Odyssey (and The Iliad as well) arose from oral tradition. Stock phrases, types of episodes, and repeated phrases such as "early, rose-fingered dawn" bear the mark of epic storytelling. Scholars agree, too, that this tale of the Greek hero Odysseus's journey and adventures as he returned home from Troy to Ithaca is a work of the greatest historical significance and, indeed, one of the foundations of Western literature.

Plato ranks among the most familiar ancient philosophers, along with his teacher, Socrates, and his student, Aristotle.

In addition to writing philosophical dialogues - used to teach logic, ethics, rhetoric, religion, and mathematics as well as philosophy - he founded Athens' Academy, the Western world's first institution of higher learning.

Aristotle was born in the Macedonian city of Stagira in 384 BC, and died in 322. He studied in Plato's Academy in Athens and later became tutor to Alexander the Great, before establishing his own school in Athens, called the Lyceum. His writings, which were of extraordinary range, profoundly affected the whole course of ancient, medieval and modern philosophy. Many of them have survived, including The Nicomachean Ethics, The Politics and Poetics, among others.

Marcus Aurelius Antoninus was born in AD 121, in the reign of the emperor Hadrian. At first he was called Marcus Annius Verus, but his well-born father died young and he was adopted, first by his grandfather, who had him educated by a number of excellent tutors, and then, when he was sixteen, by Aurelius Antoninus, his uncle by marriage, who had been adopted as Hadrian's heir, and had no surviving sons of his own. Aurelius Antoninus changed Marcus' name to his own and betrothed him to his daughter, Faustina. She bore fourteen children, but none of the sons survived Marcus except the worthless Commodus, who eventually succeeded Marcus as emperor.

On the death of Antoninus in 161, Marcus made Lucius Verus, another adopted son of his uncle, his colleague in government. There were thus two emperors ruling jointly for the first time in Roman history. The Empire then entered a period troubled by natural disasters, famine, plague and floods, and by invasions of barbarians. In 168, one year before the death of Verus left him in sole command, Marcus went to join his legions on the Danube.

Apart from a brief visit to Asia to crush the revolt of Avidius Cassius, whose followers he treated with clemency, Marcus stayed in the Danube region and consoled his somewhat melancholy life there by writing a series of reflections which he called simply To Himself. These are now known as his Meditations, and they reveal a mind of great humanity and natural humility, formed in the Stoic tradition, which has long been admired in the Christian world. He died, of an infectious disease, perhaps, in camp on 17 March AD 180.

Niccolò di Bernardo dei Machiavelli (3 May 1469 - 21 June 1527) was an Italian philosopher, humanist, and writer based in Florence during the Renaissance.

He is one of the main founders of modern political science. He was a diplomat, political philosopher, playwright, and a civil servant of the Florentine Republic. He also wrote comedies, carnival songs, poetry, and some of the most well-known personal correspondence in the Italian language.

Dante Alighieri was born in Florence Italy in 1265. In 1301, a political dispute lead to his exile from Florence.

Over the next few years he made his home in Verona, Lucca and other cities. By 1310 he had written Inferno and Purgatorio, the first two books of his Divine Comedy.

He wrote the third and concluding book, Paradiso, in the years after he found sanctuary in Ravenna in 1318.

An allegorical account of his wanderings in a spiritual wilderness and eventual salvation under the guidance of his beloved Beatrice, The Divine Comedy is recognised as Dante's masterwork and a landmark of world literature. He died in exile in 1321 and was buried in Ravenna.

The greatest German literary figure of the modern era, Johann Wolfgang von Goethe (1749–1832) was a poet, playwright, novelist, scientist, critic, theater director, and statesman. He is best known for Faust, which he started at the age of 23 and finished shortly before his death, 60 years later.

The Sorrows of Young Werther, written at the age of 25, quickly achieved cult status and remains an exemplar of the Sturm und Drang literary movement. In addition to hundreds of poems of all kinds, Goethe wrote a series of classic memoirs of his childhood and travels as well as numerous essays on scientific subjects.
