The leitmotif of this publication are the words of Aristotle: 'The assessment of a house belongs not only to the one who built it but it will be judged even better by the one who uses it (...) similarly the helm will be better assessed by the helmsman than the shipbuilder. and the feast by the guest than the cook'. This view has been cited in order to recollect that for centuries the region of Lower Silesia has been passing from hands to hands, constantly changing its affiliation. Consequently, it became the site of valuable spiritual and material culture, but also has suffered enormous and irreparable losses. Until recently, the reaction to these multicultural and multiethnic features differed; today, it has assumed quite another form. At present, the purpose of numerous initiatives in Lower Silesia is care for local cultural heritage. Attempts are being made, some of them highly successful, to regain monuments of material culture of value for the region; years later, they are returning to their proper sites as missing elements of the Lower Silesian heritage. They include : - the Breviary, a liturgical book containing the texts of the canonical hours from the first half of the fifteenth century, purchased by Andreas Wirzbach. At the beginning of 2005, and with the assistance of the Ministry of Foreign Affairs, the Breviary returned from the United Kingdom to Wroclaw; - the Vit Saraval collection composed on 34 priceless Hebrew manuscripts and part of the incunabula, i. e. prints originating from prior to 1501 and restored to Wroclaw on 9 December 2004; - the 'Treasure of Wroclaw', presented to the Municipal Museum in Wroclaw on 18 May 2006 . Its acquisition would have been impossible without the magnanimity and contribution of the population of the region. The spontaneity and generosity of the sponsors express a supreme form of patronage. These valuable museum exhibits - relics of culture of the past - now take part in the construction of the identity of the region and its historical continuum.
