In Barbara W. Tuchman’s "A Distant Mirror: The Calamitous 14th Century," the author describes Coucy as not only a man of significant wealth and grand estates but also someone who commanded a personal charm that drew people towards him. This ability significantly contributed to his standing and influence among his peers during a tumultuous time. Coucy's presence was more than just material wealth; it was his charisma and interpersonal skills that enabled him to navigate the complexities of his era.

The text suggests that Coucy's capacity to avoid making enemies further enhanced his power and stability. In a time marked by conflict and strife, his unique blend of affluence and social adeptness made him an influential figure. Tuchman illustrates how such personal traits could lead to prominence and a lasting legacy despite the surrounding difficulties of the 14th century.
