Exeter Book: The Exeter Book, Exeter Cathedral Library MS 3501, also known as the Codex Exoniensis, is a tenth-century book or codex which is an anthology of Anglo-Saxon poetry.  It is one of the four major Anglo-Saxon literature codices, along with the Vercelli Book, Nowell Codex and the Cædmon manuscript or MS Junius 11.  The book was donated to the library of Exeter Cathedral by Leofric, the first bishop of Exeter, in 1072.  It is believed originally to have contained 131 leaves, of which the first 8 have been replaced with other leaves; the original first 8 pages are lost.  The Exeter Book is the largest known collection of Old English literature still in existence.

Walter de Stapledon: Walter de Stapledon (or Stapeldon) (1 February 1261 – 14 October 1326) was Bishop of Exeter 1308–1326 and twice Lord High Treasurer of England, in 1320 and 1322.

Exeter Cathedral: Exeter Cathedral, properly known as the Cathedral Church of Saint Peter at Exeter, is an Anglican cathedral, and the seat of the Bishop of Exeter, in the city of Exeter, Devon, in South West England.

Exeter Cathedral astronomical clock: The Exeter Cathedral Astronomical Clock is a fifteenth-century astronomical clock in Exeter Cathedral, England.

Trompette militaire: The trompette militaire is a loud majestic sounding organ stop, with brassy, penetrating tone.  It is noted for its installation in Liverpool Anglican Cathedral, on the fifth manual of the Henry Willis Organ in St Paul's Cathedral, London, and in the 1968 rebuild of the organ of Exeter Cathedral.  At St Paul's, the stop was a gift of Henry Willis at the time of the 1930 rebuild, the pipework being bought in from America and placed with 30 inches of wind pressure in the North East Quarter Gallery in the Dome.  The Liverpool trompette militaire was the gift of Professor Alan Dronsfield and was installed in the Corona gallery, 100 ft above the cathedral floor, in 1997.  Until comparatively recently, the organ of Exeter Cathedral also had a trompette militaire in the minstrels' gallery above the nave.  In the most recent rebuild of the Exeter instrument the stop has been renamed simply "trompette" and has been complemented with a diapason chorus forming a nave division, all playable from the main console on the medieval screen.

Devon County War Memorial: The Devon County War Memorial is a First World War memorial, designed by Sir Edwin Lutyens and situated on the cathedral green in Exeter, the county town of Devon, in the south west of England.  It is one of fifteen War Crosses designed by Lutyens to a similar specification, and one of two to serve as a civic memorial in a city.  The first proposal for the county's war memorial was to complete the construction of a cloister at Exeter Cathedral to be dedicated to the Devon's war dead, but this scheme was abandoned due to lack of funds.  After considering multiple proposals, the Devon County War Memorial Committee commissioned Lutyens to design a War Cross instead.  The committee chose to site the memorial on the green of Exeter Cathedral after scouting several locations.  A war memorial for Exeter itself was being considered concurrently, but the committees for the two projects failed to work together, resulting in two separate memorials—the county memorial by the cathedral and Exeter City War Memorial in Northernhay Gardens.
