Elias Ashmole,
The History of the Most Noble Order of the Garter
“ The Offering of Atchievements. § 3. A third Honour paid to the defunct Knight, is a most solemn Offering up his Atchievements at the High Altar; namely, the Banner of his Arms, his Sword, Helmet, and Crest, with its Mantlings; all which had been set up over his Stall at his Installation. The Ceremony of Offering these Ensigns does not appear to have been regulated at the Institution of the Order, but rather added as an additional Honour, by King Henry V. and the manner thereof set down in the fourteenth Article of his Body of Statutes. ”
