Quadratus of Athens

Quadratus of Athens (Ancient Greek: Κοδρᾶτος; fl. 2nd century) was an early Christian apologist, traditionally regarded as a disciple of the Apostles and one of the Seventy Disciples. He is best known for presenting an apology to Emperor Hadrian during his visit to Athens around 124–125 CE. His work included a defense of the Christian faith against its critics, what he saw as the enduring impact of Jesus' miracles.

Quadratus is also associated with the apostolic tradition and is recognized as the Bishop of Athens, succeeding Saint Publius. His feast day is observed on September 21 in the Catholic Church and the Eastern Orthodox Church.
