In the footsteps of ancestral knowledge in Alexandria
« Alexandria, a city where knowledge and wisdom found their greatest temple. »— Inspired by the writings of Greek scholars
The Lost Splendor of Alexandria
Founded by Alexander the Great in 331 BC, Alexandria quickly became the cultural and intellectual capital of the Hellenistic world under the Ptolemaic dynasty. Its jewel, the Great Library, was the largest repository of knowledge in antiquity, attracting the greatest minds of the era, from Euclid to Eratosthenes. Its Lighthouse, a marvel of engineering, guided ships and symbolized the city's power and innovation.
However, Alexandria's grandeur did not last forever. Fires, earthquakes, and conflicts gradually ravaged these monuments. The Library suffered significant losses, notably during the Roman civil war in 48 BC. The Lighthouse, weakened by earthquakes, finally collapsed in the 14th century. The knowledge contained in the scrolls and papyri was dispersed or lost, leaving behind a fascinating enigma about what might have been saved.
