An archive can equal a number of different philosophical equations. For example, prior to ascension of the Papal state, all Donatello's workshop pieces along with the work of Settignano would have been stored and stacked up as an archive in storage in the basement, more to keep Donatello's clay pieces moist. Other archives could for a naturalist equal several species of plants, this you would find in a native forest as well as several species of native bird life. Some forests, especially those in Italy would have wild boar to sent the truffles and also earlier would have had small brown bears.
