The early Christian Church was very favourably disposed towards Seneca and his writings, and the church leader Tertullian possessively referred to him as "our Seneca". By the 4th century an apocryphal correspondence with Paul the Apostle had been created linking Seneca into the Christian tradition. The letters are mentioned by Jerome who also included Seneca among a list of Christian writers, and Seneca is similarly mentioned by Augustine. In the 6th century Martin of Braga synthesised Seneca's thought into a couple of treatises that became popular in their own right. Otherwise, Seneca was mainly known through a large number of quotes and extracts in the "florilegia", which were popular throughout the medieval period. When his writings were read in the later Middle Ages, it was mostly his "Letters to Lucilius"—the longer essays and plays being relatively unknown.
