A myroblyte (/ˈmɪrəblaɪt/; 'whose relics produce myron';[1] from Byzantine Greek μυροβλύτης, muroblútēs, Latin: myroblyta; Church Slavonic: мѵрото́чецъ; Romanian: izvorâtor de mir; Georgian: მირონმდინარე) is a Christian saint from whose relics or burial place "an aromatic liquid with healing properties"[2] or "holy water (very much like myrrh)",[3] known as the Oil of Saints, "is said to have flowed, or still flows",[4] or from whose body emanates a scent known as the odor of sanctity.
[5][6][7] The exudation of the oil or scent itself is referred to as myroblysia[8][9] (from Greek μυροβλυσία, muroblusía) or myroblytism.
In the Eastern Orthodox Church, some icons are also believed to release the oil.
[2] "Gregory of Tours (De Gloria martyrum, xxx: Patrologia Latina, LXXI, 730) testifies that a certain substance like flour emanated from the sepulchre of John the Evangelist.
The same Gregory writes (ibid., xxxi) that from the sepulchre of the Apostle St. Andrew at Patrae emanated manna in the form of flour and fragrant oil.
