It was dedicated to the goddess Athena, and built to ensure the victory of Athena, and so victory would not escape her. In the imagery-filled Greek language, that translates to "wing-less victory." The Temple of Athena Nike was built in 424 BC and considered the oldest temple on the Acropolis.
Many of the statues and plaques from the temple were moved to the New Acropolis Museum, located at the bottom of the hill.
This is a temple with 4 columns at the front, and 4 in the back, as referred to in ancient Greece, "tetrastyle amphiprostyle." The pediments are in the Greek style, and the pediments on the extreme columns are longer than the rest, to blur the lines between the different shapes.
The temple is known mainly for its plaques on its railings, "Nike railing." Most of the plaques today have been moved to the New Acropolis Museum, located at the foothills of the mountain.
Theseus left to kill the Minotaur, after he was informed that Minos taxes Athens, by taking a sacrifice once every 9 years, 7 boys and 7 girls, to sacrifice to the horrible creator in his palace. Instead of fighting Minos, with his strong army, Theseus went to kill the Minotaur himself.
Theseus, who succeeded in his mission, escaped Crete together with Ariadne, his love, and returned to Athens by sailing. For his happiness in his victory, he forgot his promise to his father, that if he kills the Minotaur, he will signal so from afar by spreading open white sails over his returning boats. The boats were left with their black sails.
Picture Aegeus, standing here, on the Acropolis, worriedly waiting for his son's return. When he saw the black sails on his son's boats, Aegeus assumed that his son Theseus had died. He then committed suicide and jumped into the ocean, ever since then, the body of water was named after him, the Aegean Sea. Only when Theseus returned to the city, did he understand the impact of his mistake, and was very saddened.
