Dalby arms, detail from monument in York Minster to Thomas Savage, Archbishop of York 1501-7, showing arms of Thomas Dalby, Archdeacon of Richmond 1506–1526. The wheat-garb (impaling his personal arms) is stated in various antiquarian sources to be the heraldic device of the Archdeaconry of Richmond
Coat of arms of Thomas Dalby (d.1506), Archdeacon of Richmond:  Gules, a chevron ermine between three round buckles or (Burke, Sir Bernard, The General Armory, London, 1884, p.257). Arthur Perceval Purey-Cust, Heraldry of York Minster, 1890-96, p.78[1]: "At the south-west corner of the monument to Archbishop Savage (Archbishop of York 1501-1507) there is a figure of an angel holding a shield emblazoned with arms similar to those which were on Thomas Dalby's monumental tablet, viz., a garb impaling a chevron ermine between three buckles. The latter is the cognizance of Dalby, but it is difficult to identify the former accurately. Torre, in his MS. history of the Minster and its property, mentions this coat as existing in the prebendal house of Stillington, " in the hall window," " in the window" of the dining-room above stairs," and carved in stone on the chimney-piece of the same, with another shield containing a garb only. He thus labels them " Richmond Archdeaconry impaling Dalby." For want of more definite information I must accept his statement, but neither in the Diocesan Record Offices of York or Chester, nor in the British Museum, can I find any seal shewing what the device of the Archdeaconry of Richmond actually was."
