Greek culture has many examples of classicism, especially in the arts. They were a very original culture in their way of life. A good example is the Parthenon. It towers in height with it's beautifully elegant and simple design. It served as a shrine to Athena, the goddess of wisdom and war. Many people visit it each year for it's history and unique structure. It had a columned design, made marble and realistic lifelike sculptures the first of it's kind. Greek architecture has a specific look and feel to it that has been repeated in inspiration of many artist. It has been used as a design for many current structures, including banks, and libraries.
The Iliad, and the Odyssey, are very unique epics that are the first of their kind. They tell stories that the Greeks held close and wanted to last forever within their culture. These are even used for inspiration today in writing and poetry. Both are also taught in high school, in basic literature classes. They carry lessons, that we use in today's culture, like the concepts that everyone makes mistakes (even heroes), to follow directions, loyalty, and to never give up or let go for the ones that you love. All of these life lessons are very important in our culture today.
Greek art also has great examples of classicism. One great example is Greek pottery. They gave a unique design that usually depicted a story of some kind, many repeating the Iliad and the Odyssey. It would also show great stories about their gods and goddesses, how things came to be, why things are the way they are, and why they are here. Many pottery told tales of great heroes that greatly influenced the Greek culture. An example would be a krater (pot used for mixing wine and water), that depicts Sarpedon (warrior and Trojan ally) being carried from battle by Hypnos, the god of sleep. Although the firing methods of making ceramics are different today, the designs of Greek pottery are still repeated by artist.
Greek philosophy also carried original aspects. The Greek believed that there was a force that guided the forces of nature, that made the laws and rules for things to be the way they are, and what they would become. This has become the basis of many religions, if not almost all the current religions of the day. Hinduism, and Christianity heavily rely on this concept, along with many current pagan traditions. It also carried into current entertainment, even movies, "Star Wars" greatly relies on the idea of a strong "force" giving them power and governing their nature. Greek philosophy also brought the philosophy of great thinkers like Socrates, Confucius, Plato, and Aristotle who's ideas are still relied on today.
Greek mythology is also very original and still used today. Besides many gods and goddesses being used in many versions of modern paganism, including the modern Wicca, the concept of a "muse" is used with people who don't carry beliefs in Greek mythology. The muse has been known to give artists inspiration, artist still use this concept today. If they somehow receive a great idea, a muse is what they refer to. Many artists long for a muse to come along and give them inspiration. Many no longer look at the muse as something divine, but more as of a concept of inspiration.
Greek culture has greatly influenced current culture. From it's literature, it's art, philosophy, and mythology, Greek culture will continue to effect modern life.
