Seals are one of the specific sources which can be used to study medieval history. The seals of ecclesiastical institutions and ecclesiastical individuals form a big and an exceptional group in terms of iconography. A necessary condition for their use is first and foremost to make them accessible to professional researchers, to study and analyse them and publish the findings. The following text introduces a few fragmentary sources, the seals of the Church representatives from Spiš dated to the 14th and 15th centuries. The seals of three representatives of the religious orders (Benedictines, Cistercians and the Canons Regular of the Holy Sepulchre) and three priests of the Spiš parishes are presented. The seals were part of four documents made in a privilegial way. The contribution focuses sigillographic and iconographic analysis of the mentioned seals.
