Silva rerum or the forest of thing was a one-of-a-kind book where Polish nobility used to (in XVI-XVIII centuries) note everything that seemed interesting, important, bizzare or for some other reason worth recording. They covered all areas of the family life, starting with financial documents and economical information, through practical advices and recipts, ending with jokes and gossips. Every silva rerum was different, every silva rerum was unique and so mine will be. Enjoy.
