An early London reprint of the important first Mai edition of Cicero's De Re Publica (initially published the previous year in Rome). Angelo Mai (1782-1854) was able to rediscover a number of works thought lost during his time running the Ambrosian Library in Milan and then the Vatican Library in Rome through his use of chemical treatments on ancient manuscripts. Among his discoveries were substantial, previously-unknown, fragments of Cicero's De Re Publica, making his edition one of the most important in the modern era.
