This is an amateur translation/summary of a site from http://www.pigizois.gr/ (http://www.pigizois.net/agioi/6agioi_megara/6martires.htm), which is itself derived from:
Kontakion (amateur translation)
Let us praise the protectors of Megara, with Demetrios the noble, and steadfast Basil and Polyeuctos, Saranti, Adrianos and Seraphim, the light-bearing, and Dorotheos, and divine Platon, George, Iakovos, crying out: Hail, O Godly-chosen rank!
Megalynarion (amateur translation)
Hail, radiant flames of Megara, that shine with incorruption, shining upon the faithful, shining with new lights of salvation, O Ten Martyrs, ever-radiant phalanx.
The relics of these saints were also found in a wondrous manner. In the year 1754, a cleric named Oikonomos (which could have something to do with being "Oikonomos" of the Patriarch of Jerusalem) wanted to build a house. When the workers of the community were digging and constructing the foundations, one of them claimed that he felt an intense heat at his feet, and indicated that he couldn't keep working. The Oikonomos put his hands in the spot, and paradoxically felt the same heat as the worker. The rest of the workers, however, kept digging until they hit a marble slab with the following inscription on it: "Λείψανα Μαρτύρων. Αδριανός, Πολύευκτος, Πλάτων, Γεώργιος" [The relics of the Martyrs Adrianos, Polyeuctos, Platon, George]. Lifting up the plaque, he found the all-holy relics of the Holy Four Martyrs, and he glorified God for the heavenly blessing and consolation which he granted to them. In the place where the relics were found, further excavations revealed a large Early-Christian Basilica which dates from the mid-5th to the 6th century AD, and which was built in honor of the Four Holy Martyrs. This filled the residents of Megara with joy, but also brought temptation, as someone during the night stole the majority of the relics and fled for the Peloponessus. However, a few smaller pieces of the relics remained, and the Oikonomos took the marble plaque to Constantinople to show the Patriarch and tell him about these occurences. Further excavations in 1998 uncovered more of their holy relics, which were placed in a beautiful reliquary and are honored joyously by the faithful. Their feast is celebrated on February 1st.
Apolytikion of the Ten Martyrs of Megara in the First Tone (amateur translation)
Let us all hymn the decade of Martyrs, Dorotheos the divine, Seraphim and Iakovos, Demetrios, the noble Basil, Polyeuctos and Platon, with Saranti, George the steadfast, and Adrianos, crying out: hail, Martyrs of Christ, hail unassailable towers, encircle the city of Megara with safety through your prayers.
