The dedicatory donation of valuables by the faithful is an ecumenical and timeless phenomenon among religious people. In Orthodox Christian communities these objects, commonly known as 'tamata' (i.e. promised offerings), are offered by the faithful to express gratitude to Christ, the Virgin Mary, or a Saint, for the help they received following their prayers. These tamata may be objects made with precious materials, or at times made with ones that are cheaper but with great sentimental value for their donors. Examples include jewellery, ecclesiastical vessels, icons, etc. Furthermore, manuscripts that have survived to this day contain deeds of donation to churches which attest the cases of donors who even donated real estate assets.
