I’ve seen enough period art to convince me that “shining armour” was often a lot darker than the chrome-plated image which the term suggests.
I’ve also long thought that the whole business of “knights in shining armour” wasn’t a medieval concept at all, certainly not the default one, but was a Regency / early Victorian fictional conceit from Romance poets and Sir Walter Scott’s historical fiction. (About 10 years ago an actual expert said more or less the same thing, leaving actual amateur me feeling rather smug…) :->
This illumination features armour that’s black or dark blue in colour, but with the carefully-delineated highlights of a shiny surface. There are many other like it.
Armour was coloured for both decorative and practical purposes; chemical blueing with acid produces a very dark, lustrous and effectively rust-resistant finish like the one in the medieval illustration. I once had an Arms & Armor rapier with that finish on the hilt: it looked like this…
Heat-blueing, which was more blue than black, was a popular treatment for Greenwich armour of the Elizabethan period, as was browning and russetting (all of which were and are used on firearms), processes which used heat, chemicals or controlled “good rust” to create colour and also prevent uncontrolled “bad rust”.
Here’s the helmet of Sir James Scudamore’s Greenwich harness, which was once blued and gilt.
The image on the left is how it looks now, after being thoroughly scrubbed with wire wool, sand or other abrasives at some stage in the 19th century to make it “shining armour”. The image on the right is a CGI restoration of its original appearance, based on still-visible traces of colour in the grooves beside the gold strapwork.
Here’s the browned and gilt “garniture” (armour with extra bits for different styles of combat, like a life-size action figure) of George Clifford, Earl of Cumberland. I don’t think grinding this beauty down to bright metal would be an improvement…
Henry VIII’s tonlet (skirted) armour for foot combat at the Field of the Cloth of Gold now looks like this:
Originally it would have been shiny black or dark blue with gilt details and the engraved panels picked out in coloured paint or enamelling - red Tudor Roses, green leaves etc., but that wasn’t “shining armour”, so…
This detail shot shows the fine score-marks left after it was sanded “clean”, with dark pigmentation in the grooves as a memorial of how it once looked.
This Renaissance painting, “Portrait of Warrior with Squire”, shows black armour on the warrior and bare-metal armour on his squire, so it’s clear that armour in art wasn’t painted black simply because artists couldn’t properly represent burnished steel.
In this article, Thom Richardson, Keeper of Armour at the Tower of London and Royal Armouries in Leeds (the actual expert I mentioned at the beginning) comes straight out and calls Scott responsible for “shining armour” vandalism:
The sets of armour are not in their original black and gold because of over-aggressive polishing in the 19th century when, said Richardson, “they were polished with brick dust and rangoon oil to within an inch of their life” to fit the aesthetic of what armour should look like, all shiny and silvery. “Walter Scott is to blame,” Richardson added ruefully.
Scott can also be blamed, according to the Oxford English Dictionary, for creating or at least popularising that clunky, inaccurate term “chain-mail”. It cites the first appearance in 1822 (recent when talking about mail) when a character in “The Fortunes of Nigel” says:
“…the deil a thing’s broken but my head. It’s not made of iron, I wot, nor my claithes of chenzie-mail; so a club smashed the tane, and a claucht damaged the tither.”
Plate armour was also painted, either crudely…
…or with much more care (this style is actually called black-and-white armour); since the paint was oil-based, it also had a rust-proofing effect…
I have a notion that the more white there was on black-and-white armour, and thus the more work (by servants, of course!) needed to keep it looking good, may have been an indication of rank, status or success. Just a guess…
Armour left rough from the hammer - therefore cheaper than armour polished smooth, since every stage of the process had to be paid for - was also treated with hot oil in the same way cast-iron cookware is seasoned, again to prevent rust.
There were terms for bright-metal armour - “alwyte harness” and “white armour” - but the existence of such terms suggests to me that they arose from a need to describe an armour finish which needed a tiresome amount of maintenance to keep it that way. I’m betting that the last stage of a clean-and-polish was a good layer of grease, or even a beeswax sealant like the coatings used by museums today.
White armour may have been a demonstration of wealth or conspicuous consumption in the same way as black or white clothes: one needed servants constantly busy with polishing-cloths, the others needed really good colour-fast dye or lots of laundering, and all of those cost money.
One thing is certain: a knight in shining armour wasn’t the one who sweated to keep it shining. That’s what squires were for…
