Unlike the other works in the series, there are a few books in the 〈Library-Triangle zone〉. There are three desks, three books, and three potted plants, giving the work more space than the others that fill the screen. On the desk in the foreground, Vanitas’ painting elements, skulls, and books, appear. Books contain a wealth of information, including human knowledge, culture, and history, and even books written in the past can be passed on to future generations. Therefore, books transcend time and space and become a medium to connect the past and future.
