The term may have come from the fact that 'holystoning the deck' was traditionally done on one's knees, as in prayer.^[1]

According to one source holystoning was banned in the US Navy in 1931 as it wore down the decks (and with the demise of teak decked battleships became unnecessary).^[1] However, a photo on the US Navy's Navsource photo archive of the USS Missouri) purports to show Navy Midshipmen holystoning the deck of the USS Missouri in 1951 (albeit in a standing position)^[2] A Time Magazine article (June 8, 1931) discusses the end of holystoning (archive article (fee) ) in the US Navy.

John Huston's 1956 film Moby Dick,^[3] and most recently Peter Weir's 2003 film Master and Commander: The Far Side of the World,^[4] shows sailors scrubbing the deck with holystones. Holystoning is referenced in Richard Henry Dana's diary, the 1840 classic Two Years Before the Mast in what he calls the "Philadelphia Catechism":^[5]

“Six days shalt thou labor and do all thou art able,

And on the seventh—holystone the decks and scrape the cable.”
