The impression of Roger that the author gives by describing him as a frail and willow-wild is the impression of <em>someone weak.</em>
Explanation:
After reading this description done by the author, the reader can infer that <em>Roger is a weak person, not only in his wills but also in his appearance.</em> By saying that someone is <em>frail</em> and <em>willow-wild</em>, we're describing someone whose body is fragile, someone that is probably not well eaten and dizzy. We, as readers, can imagine someone thin and maybe misaligned, <u>weak in temper and health.</u>
Humanism, a Renaissance value, is the belief that "the human being is the measure of all things," that people and their activities are important and interesting.
