Caesarius of Arles (; 468/470 27 August 542 AD), sometimes called "of Chalon" (Cabillonensis or Cabellinensis) from his birthplace Chalon-sur-Saône, was the foremost ecclesiastic of his generation in Merovingian Gaul. Caesarius is considered to be of the last generation of church leaders of Gaul who worked to promote large-scale ascetic elements into the Western Christian tradition. William E. Klingshirn's study of Caesarius depicts Caesarius as having the reputation of a "popular preacher of great fervour and enduring influence". Among those who exercised the greatest influence on Caesarius were Augustine of Hippo, Julianus Pomerius, and John Cassian. The most important problem for Caesarius was the efficiency of the bishop's fulfillment of his pastoral duties. By that time, preaching had already become part of the standard church service in Gaul; many bishops recognized the importance of such a means of educating morality and encouraged it. However, Caesarius' enthusiasm was outstanding in its own way, and he urged his clergy to preach as often as possible, in the church and outside it, to the willing and the opposing. Caesarius' sermon topics generally dealt with moral issues. Life Caesarius was born at what is now Chalon-sur-Saône, to Roman-Burgundian parents in the last years of the Western Empire. His sister, Caesaria, to whom he addressed his "Regula ad Virgines" (Rule for Virgins), also presided over the convent he had founded. At the time of his birth, Germanic kings de facto governed Burgundy despite nominal Roman administration. Unlike his parents, Caesarius was born with a very strong and intense feeling for religion which alienated him from his family for the majority of his adolescence. Caesarius left home at seventeen and studied under Bishop Sylvester for a few years. Afterwards, he found his way to Lérins (Lerinum), an island monastery, which was known to be a major dynamo for creative forces of work in the Church of Roman Gaul. After training as a monk at Lérins he devoted himself to reading and applying the scripture in hopes of improving the quality and organization of Christian life and serving the poor. He rapidly became master of all the learning and discipline the monastery communicated and was appointed cellarer. However, he proved unpopular at Lérins when, as cellarer of the monastery, he withheld food from monks because he felt they were insufficiently austere. As a result, the abbot Porcarius removed Caesarius from his post, whereupon he began starving himself;
