In the ancient world, letters were rare treasures, often costly and complex to send. Imagine this: fewer than 14,000 letters have been recovered from antiquity, most ranging from a mere 20 to 200 words. Yet, a few philosophers—like Cicero, whose longest letter spanned 2,500 words, and Seneca, with a 4,000-word letter—wrote epistles that defied the norm. Then there’s Paul, the Apostle, whose letters not only bridged distances but profoundly shaped Christian thought.
