Sources and Identity
The memory of New Martyr Habakkuk rests entirely on a remembrance found in codex M. Lavra Omega 89, folio 155, dated to the seventeenth century. Because no narrative of his sufferings was preserved, he is absent from the standard synaxaria, and the surviving record gives little beyond his name, the place and date assigned to his witness, and his designation.
His name was first brought into hagiographical literature by Metropolitan Sophronios Eustratiades, who also published a catalogue of the manuscripts of the Great Lavra, where the remembrance of Habakkuk's martyrdom is found.
From the title 'Venerable' attached to his name, it has been inferred that Habakkuk was a monk, most probably of Mount Athos, though the manuscript does not state this explicitly.
