Hellenism

Hellenism in Greece was a period between 507 BCE and 323 BCE when Alexander the Great was ruler and the Greek culture experienced its Golden Age of literature, language, art, and innovative technology. It spread through the Greek mainland, Crete, and the coast of Asia Minor, and was the era in which the gods played a major role in the Greek's daily lives.

Winged Victory of Samothrace: Also known as the Nike, this statue is one of the most recognized and praised pieces of art from the Hellenistic period. In white marble it portrays the Nike goddess/spirit known for her strength, speed and victories. It's unsure the reason for the statue's make, but we can guess it was made for the memorial of a victorious battle and perhaps a close appreciation for the gods and their strong religious ties to the Greeks.

Ganymede Jewelry: Made of gold, rock crystals, and emeralds, these pieces of jewelry were located in Macedonia. Many of these pieces retain religious aspects; the bracelets, and terminals have intricate designs of ivy and grapes, a representation of Dionysus god of wine, and the earrings are tiny images of Ganymede, a beautiful Trojan prince whom Zeus brought back to Olympus to be a cup-bearer for the gods.

Venus de Milo Statue: Found on the island of Melos, this sculpture has intrigued many who have come to pass it. It's unsure whether it represents the half-naked goddess Aphrodite, or the sea goddess Amphitrite. It was presented it to Louis XVIII in 1820, devoid of the woman's arms and the jewelry it was believed to have worn at its time of making.

Boy Jockey and Horse: The bronze sculpture was lost for a long time during a ship wreck during 146 BC, so once found (in two separate pieces), archaeologists confirmed that its realistic shape and culture could only place it during the Hellenistic period. It depicts an African boy, perhaps a slave or a trained jockey, memorializing a race victory. It represents the popularity of sports during this Golden Age such as Greek horse races.

Terracotta Funerary Urn: It's common that during a society's period of prosperity, burials of their dead become more intricate. This is the same for the Greeks; they cremated their dead and saved their ashes in these exotic urns that varied in shape and image. Most, if not all funerary urns were found with Greek epics and violent drama.

The Three Graces Statue: Depicting the Three Grace of Beauty, Mirth, and Abundance (Aglaia, Thalia, and Euphrosyne) who were handmaidens of Aphrodite, the statue is a very popular image of the sisters used in all aspects of Greek culture. They are also closely connected to music and dance which were growing arts during the Golden Age in Greece. It's also another piece of evidence that mythology played a big part in their lives.

Bronze Statuette of a Veiled and Masked Dancer: Dressed in a mantle and several other layers of clothing, the figure is either a professional entertainer or a combination of dancer and mime, famously found in the city of Alexandria. The statuette is believed to have been created around 225 BC to be put in a temple. This is just one example of the Hellenistic culture in their sculptures. Opposing the classic Greek style of beauty and perfection, many artists focused realistic, everyday people.

Laocoön and His Three Sons Statue: This sculpture is actually made of seven separate pieces of marble locked together and depicting an important mythological scene: Laocoön, a Trojan priest, interfered in battle plans when Troy was under siege. In response, Athena punished him by sending the sea serpents, Porces and Chariboe to attack him and his two sons. This is an important scene because it maintained both social and religious significance to the people.

Vix Krater: The creation of large metal vessels, especially the one above made from beaten bronze was another trait of Greek expression during the Hellenistic period. Many, such as this one contained friezes of fantastical creatures that emphasized the Greek's relief in their artistry and of which very rarely survived in any discovered artifacts. The Vix Krater is believed to be used for mixing water and wine, and due to evidence of being traded over great connections between other societies, these metal vessels were possibly seen as high-status gift exchanges for wine and raw goods.

Gold-Glass Alabastron: Made from alabaster, a soft white/clear stone abundantly used in Egypt, these containers grew slenderer as the Hellenistic period transgressed, transitioning into an important household object across the Mediterranean, used to hold rare, expensive perfumes and oils.
