We also have to remember to look at it within the context of the specific period as well. The gold and jewels and finery all pertain to a 14th century knight, but if you go back to the 11th century, the bar was probably a little lower.
Agreed. It's difficult to determine materials from effigies, since they aren't colored, but here's some period artwork as examples. They're all early 16th century, which I know is later than 14th century, but good artwork from those centuries is something I don't know much about...
Portrait of a Knight of the Order of St. StephenMichele Rosini (Michele di Ridolfo del Ghirlandaio) (1503-1577)
Relatively plain armor, no etching, no vast seas of gold; some brass or gold roped trim with leather edging.
Portrait of a Knight, Barthel BruynBarthel Bruyn (1493-1555) (painted: 1531)
Simple fabrics, no rings, a gold necklace, a simple fur
A Knight of the Rehlinger FamilyUnknown German Artist, 1540
Fancy Maximillian style, which would have been waning out of popularity in 1540. It's nicely etched and fluted, but no gold or jewels.
Portrait of a knightVittore Carpaccio, 1510
Still in schynbalds long after they went out of fashion, when even basic men at arms were wearing cased greaves; simple scabbard, simple cuirass with some rolling and recessed edges, and basic decoration on the rest.
A Knight with his Jousting HelmetGiovanni Battista Moroni, 1554-58
Simple black clothing, and his helmet and the armor on the floor are very utilitarian with the decoration primarily being brass hinges / buckles / strap ends. He does, however, have one heck of a fancy crest. But I think this example is VERY comparable to Sir Ian's armor, with minor differences (roping, brass hardware).
Yes, there are many period armors that have all sorts of (to us) excessive decoration and all manner of fancy-shmancy stuff. But the vast majority of those that I can think of off the top of my head are literally Kings, Princes, Dukes and the upper-elites. There are plenty of surviving harnesses that don't show any of that adornment, and they are the majority, not the minority. Which is important, because armor of royalty was likely not worn as often as the knights who earned their wages in battles; King Henry had multiple sets of armor made for him that he never even wore!
Let's say out of 10 people on a battlefield, only 1 is a knight. The paintings of battles show the majority of them in full armor as similarly equipped; there aren't a hand full of them running around in parade armor. I think there's a tendency to over-romanticize and over-inflate the status and appearance of the more common knights. And the ones in the paintings are ones who had the money to spend on art work, which was probably a luxury that commoners didn't have in period.
Sir Patrick brings up some great points. I don't argue that knights didn't have a lot of money, and I don't argue that they didn't SPEND a lot of money. I think there's an over-emphasis on them spending a large sum of their money on armor fancy clothing to
look excessively wealthy, rather than having to spend it on their manor / house / farmland, horses, stables, their retinue, and so on. I think my examples from the paintings show there were
some knights who didn't look like they are featured on MTV: Cribs of Europe.
