Righteous Mary of the Don

No authoritative source (azbyka.ru, drevo-info.ru, pravenc.ru, days.pravoslavie.ru) contains any information about a "Blessed Mary of the Don." The original template carried the same 5-date cluster belonging to Blessed Mary of Diveyevo (Fedina) — these dates have been removed as certainly wrong for this card. Both "icon" images, upon inspection, turned out to be Western European Catholic paintings unrelated to any Orthodox saint: the first is Walthère Damery's "St. Dominic Receiving the Rosary from the Virgin" (17th c.), the second is a Gothic panel by Silvestro dei Gherarducci, "The Assumption of St. Mary Magdalene" (National Gallery of Ireland). Pending a reliable source, the card is honestly marked as unconfirmed and hidden from the calendar.
