Dave is off to Istanbul, once called Constantinople and once called Byzantium. Dave explores the Hagia Sophia (meaning “Holy wisdom”). The Hagia Sophia is now a museum but was once considered the most beautiful and important Christian Church in the world. Learn about Constantine-the Roman Emperor who stopped the persecution of Christians and legalized open religious expression though the Edict of Milan. Dave examines one of Constantine’s greatest achievements when he brought various Christian factions together to end what many viewed as heresy and work together to develop the Nicene Creed. Last Dave travels thru Istanbul to see the evidence of the last great battle for control of the city-a battle that officially ended the Roman Empire.
