The influence of ancient Greece and Rome on Western culture is unmatched by any other. The very words "classic" and "classical", which literally refer to these ancient states, have also come to mean "the standard" or "the best". Classicism the reverence for Greek and Roman culture, especially literature, art, clarity, and has been defining characteristic of Western culture throughout history.

After the Roman Empire fell to nomads in the early Middle Ages, few Europeans had the education of inclination to pursue the ancient wisdom of the Greeks and Romans. Their work was never lost manuscripts had been stored in medieval libraries and monasteries but Renaissance thinkers acted as if they had discovered the classics. In Italy, the birthplace of Renaissance, scholars looked first to their Roman ancestors: Livy, Ovid, Horace, Seneca, Pliny and others. The writings of Cicero, The Roman state-man, became a model for Renaissance Italian prose. Virgil, too, with his sonorous verse, became a literary hero. When Florentine poet Francesco Petrarca became poet laureate in 1341, he gave speech on Vigil in Latin.

Renaissance architects, led by 15th-century thinker Leon Bautsta Alberti, looked to the classical age for inspiration. Alberti studied ancient buildings in Rome before writing his influential. Ten Books on Architecture, which stressed proportion and harmony. In art, similar  classical ideas-harmony, balance, the glorification of the human form-inspired the sculpture of Michelangelo, The paintings of Raphael, and the works of many others.

Along with cities and rulers, writing distinguished the earliest civilizations. Writing was a skill originally confined to an elite group of officials, priest, and scribes. Writing for him who knows it is better than all other professions, declared an ancient Egyptian text, composed by a writing teacher to be copied out by scribes in training. It pleases more than bread and beer, more than clothing and ointment. It is worth more than an inheritance in Egypt, more than a tomb In the west.

The rivalry between Cain and Abel reflects a human drama played out over thousands of years in the region that gave birth to the bible. The ancient Israelites lived in the Fertile Crescent, an arc extending from Egypt's Nile Valley to Mesopotamia, between the Tigris and Euphrates rivers in modern-day Iraq. This region was not as dry in ancient times as it is today, and land unsuitable for farming could be used for grazing.

The transition from hunting and gathering to farming, which may have begun around 10,000 B.C. was a great step forward for the human race. Ultimately, it allowed the emergence of civilization. Like all profound changes, however, adapting to farming was difficult for those used to a different way of life. Farming was harder than hunting and gathering, particularly when people first began to work the soil and lacked metal tools or draft animals to ease their labors.
