Those ancient books don't have an author. I once read a book. The introduction said that the author of the book is unknown. I want to know which books don't have an author.
Ancient books without an author generally referred to those traditional literary works with a long history and wide circulation. They may not have a clear author but were jointly created or inherited by many different people or groups. This was because the creation and distribution of literary works in ancient times were mainly based on word of mouth rather than through publishing and printing like modern literary works. Although these traditional literary works did not have a clear author, they usually had relevant legends, stories, historical events, etc. as the background, as well as specific characters or schools as representatives. In some cases, these representatives might become the authors or representatives of the works. For example, some ancient novels might have a legendary character or genre as the protagonist. There were also some ancient books that did not have a clear author, but it generally meant that the history of the publication or creation of these books was not too clear. For example, some ancient novels might be the works of a certain period or a certain group, but the specific time of creation and author are not very clear. In this case, we can assume that the author of these books is unknown.
