John, the herald of the Lord and His baptizer...

(a bit late, but I just found the text –the earliest version of the event commemorated today, 24 February)

…revealed his head which, at an unspeakably horrible demand, Herodias had once accepted after it had been cut from his shoulders and placed on a dish, and buried far from his headless body. He revealed his head to two eastern monks (probably sometime in the mid-4th century) entering Jerusalem to celebrate the resurrection of Christ the Lord, so that when they reached the place where the former king Herod lived they were advised to search around and dig the ground up faithfully. So while they were journeying back to their own places, carrying in their rough saddle-bag the head they had discovered by faith, a certain potter from the city of Emesa (Homs), fleeing from the poverty which threatened him daily, showed himself to them as a companion. While, in ignorance, he was carrying the sack entrusted to him with the sacred head, he was admonished in the night by him whose head he was carrying, and fleeing both his companions he made off with it.

He entered the city of Emesa immediately with his holy and light burden, and as long as he lived there he venerated the head of Christ’s herald. At his death, he handed it over in a jar to his sister, who was ignorant of the matter. Then she left it to her heir, stored away and sealed just as it was. Next a certain Eustochius, who was secretly a priest of the Arian faith, unworthily obtained this great treasure and dispenses to the rabble, as if it were purely his own, the grace which Christ the Lord bestows on His inconstant people through John the Baptist. When Eustochius’s wickedness was detected, he was driven out of the city of Emesa.

Afterwards, this cave, in which the head of the most blessed John was set in an urn and reburied underground, became the abode of certain monks. Finally, while the priest and head of the monastery, Marcellus, was living a faultless life in that cave, blessed John, the herald of Christ, revealed himself and his head to Marcellus and showed that it was buried here, conspicuous by its many miracles. It is agreed therefore that this venerable head was found by the foresaid priest Marcellus while Uranius was bishop of the city mentioned. This was on the twenty-fourth day of February in the consulship of Vincomalus and Opilio, in the middle week of the Paschal fast, and the ruling emperors were in fact Valentinian and Marcian.
