English: The statues adorning the façade of the Library of Celsus represent the Four Virtues or the Hellenic cultural values of Celsus: Sophia (Wisdom), Arete (Bravery), Episteme (Knowledge), and Ennoia (Thought). Originally, all these statues were made of bronze but they were, most possibly, melted down after the fire of the library in the 3rd century. Sometime afterwards, they were replaced with female marble statues, evidently acquired from ruined buildings in Ephesus. Unfortunately, the statues that can be seen in Ephesus are just the modern-day copies as the originals are in the Ephesus Museum in Vienna.
