First and Second Finding of the Honorable Head of the Prophet and Forerunner John the Baptist (Feast Day - February 24)
After the Beheading of the Holy Prophet, Forerunner and Baptist John (August 29), his body was buried by disciples in the Samarian city of Sebaste, and his venerable head was hidden by Herodias in an unclean place. St Joanna (June 27), the wife of King Herod's steward Chuza (Luke 8:3), secretly took the holy head and placed it into a vessel and buried it on the Mount of Olives in one of Herod's properties.
After many years, this property passed into the possession of a government official who became a monk with the name of Innocent. He built a church and a cell there. When they started to dig the foundation, the vessel with the venerable head of John the Baptist was uncovered. Innocent recognized its great holiness from the signs of grace emanating from it. Thus occurred the First Finding of the Head. Innocent preserved it with great piety, but fearful that the holy relic might be abused by unbelievers, before his own death he again hid it in that same place, where it was found. Upon his death the church fell into ruin and was destroyed.
During the days of St Constantine the Great (May 21), when Christianity began to flourish, the holy Forerunner appeared twice to two monks journeying to Jerusalem on pilgrimage to the holy places, and he revealed the location of his venerable head.
The monks uncovered the holy relic and, placing it into a sack of camel-hair, they proceeded homewards. Along the way they encountered an unnamed potter and gave him the precious burden to carry. Not knowing what he was carrying, the potter continued on his way. But the holy Forerunner appeared to him and ordered him to flee from the careless and lazy monks, with what he held in his hands. The potter concealed himself from the monks and at home he preserved the venerable head with reverence. Before his death he placed it in a water jug and gave it to his sister.
From that time the venerable head was successively preserved by devout Christians, until the priest Eustathius (infected with the Arian heresy) came into possession of it. He beguiled a multitude of the infirm who had been healed by the holy head, ascribing their cures to the fact that it was in the possession of an Arian. When his blasphemy was uncovered, he was compelled to flee. After he buried the holy relic in a cave, near Emesa, the heretic intended to return later and use it for disseminating falsehood. God, however, did not permit this. Pious monks settled in the cave, and then a monastery arose at this place. In the year 452 St John the Baptist appeared to Archimandrite Marcellus of this monastery, and indicated where his head was hidden. This was February 24 and became celebrated as the Second Finding. The holy relic was transferred to Emesa, and later to Constantinople.

Apolytikion in the Fourth Tone
The Forerunner's sacred head, having dawned forth from the earth, doth send incorruption's rays unto the faithful, whereby they find healings of their ills. From on high he gathereth the choirs of the Angels and on earth he summoneth the whole race of mankind, that they with one voice might send up glory to Christ our God.
Kontakion in the Second Tone
Since we have obtained thy head as a most sacred rose from out of the earth, O Forerunner of grace divine, we receive sure healing in every hour, O Prophet of God the Lord; for again, now as formerly, thou preachest repentance unto all the world.
