Haluk Perk Museum in Istanbul has gained a prestigious place among the private museums of our country with its rich collection containing rare examples. The collection, which was turned into a museum by Haluk Perk in 1995, also includes many different categories of works from the Byzantine Period. In our article, a total of fifteen works from this collection, which give information about the beliefs, ascetic life, cross and pilgrimage concepts in the Byzantine world and how they are reflected in art, are discussed. Of these works, which are dated back to different periods of the Byzantine Empire, there is one pilgrim's token, two icons that are portable, nine encolpia decorated with the depictions of saints and three bronze objects of jewelry. The works in question were handled together with the concepts, people and ideas emphasizing the relationship between belief and worship in the Byzantine world in order for the rich iconography in them to gain a meaning and to be able to better comprehend what the dominant thought was in their emergence. The works, which have been examined and dated considering their iconography, styles and similar examples, are extremely important in terms of being rare and unique examples of Anatolian finds within the scope of Byzantine Art.
