  Certain aspects of medieval society (including the lives of women or slaves) are poorly documented, which limits a comprehensive study of the period. The systematic publication of medieval written sources began with the Rerum italicarum scriptores by Ludovico Muratori (d. 1750), which was followed by similar series such as the Monumenta Germaniae Historica in Germany and the Rolls Series in the United Kingdom. These large collections primarily contain annals, chronicles and other narrative sources focusing on the deeds of powerful men. Professional historians treat medieval narratives cautiously, since they are often filled with distorted facts or unrealistic information. Documents of state or church administration such as royal charters and chrysobulls are indispensable sources of medieval history, although many are forged. Other written sources include graffiti, seals, and letters.
  
  Since the 1950s, archaeology has significantly contributed to studying the history of poorly-documented regions, periods, and groups (such as peasantry); chronological dating, however, is still uncertain. Legislation may influence archaeological research. New finds of coins and hoards are frequently exhibited in jurisdictions with liberal regulation such as England and Wales, but in other countries (such as Italy) finds from unofficial excavations are seldom published. Although medieval images and sculptures may provide useful information about everyday life, a critical approach is necessary; irony, satire, and anachronism were popular stylistic devices of medieval artists.
