Portions of St. John's right hand, with which he baptised Jesus, is said to be in the possession of the Serbian Orthodox Cetinje Monastery in Montenegro, and also at the Romanian Skete of the Forerunner on Mount Athos as well. Another relic of his forearm is in a glass display case at the Seraglio (Topkapi Soray), which had been the palace of the Ottoman sultans in Constantinople following the Fall of the City.http://www.johnsanidopoulos.com/2010/01 ... ptist.html
It is not known how the portion of St. John's right hand came to be at Dionysiou Monastery on Mount Athos. What we do know is that somehow in the first years of the 19th century the advisor to Prussia in Constantinople, John Frangopoulos, was in possession of this relic and he adorned it with jewels. On 10 March 1802 it was brought (or returned) to Dionysiou Monastery through the efforts of its abbot, Joachim Agiostratiti. This event is commemorated annually by the Monastery on the Fourth Sunday of Great Lent with an all-night vigil.
