Formatted as a letter from a knight on the battlefield to his children, it describes virtues of the life of a knight as he learned them followed by brief anecdotes to complement the importance of such rules.
What I found interesting is that the narrator intended these rules, this final letter, for all of children, even the girls. Not only so they would know how to behave, how to treat others, but they in turn should expect to be treated. Although this letter was written in the 15th century, it reads, to me at least, like modern self-help books. These rules are applicable to anyone in any walk of life. I think many would benefit from reading Rules For a Knight. We can all use guidance, and we all have a knight in us somewhere.
