I am planning to commission a new harness to replace my c.1350 one, which I have decided is too heavy and lacks mobility. It is a COP and splint arm & leg harnesses, all covered with leather and fancy pewter rivet surrounds etc, all of which add weight. The full armour weighs about 40-42kg (about 90#) and all the plates are mild steel, 1.2mm or 1.6m thick. I have been using it for jousting the last two years, but also want to use my armour for foot combat tourneys, and I've realised it is both too heavy (no horse to carry it for me!) and the elbows and knees don't flex enough (no lames to increase the movements past about 100 degrees).So I've thought about commissioning a new harness of the period 1370-1375; the most advanced armours had full arm and leg harness with fans, and a globose breastplate with umpteen faulds. Now, to keep the weight down and minimise the dents it would get if it was mild steel, I have approached a friend about making it out of carbon steel. He has worked with carbon steel before, though I suspect I will be pushing harder than other clients, and he has sourced 1.2mm and 1.6mm 1070 sheet, and 2.0mm 1050 sheet for bits that need a lot of raising and finishing. My questions: - what are your general thoughts on carbon vs. mild, in terms of plate thicknesses for various parts (especially for high-impact jousting) - I intend to get the pieces shaped and articulated, and do the heat treatment and finishing myself over the next year or two. I know heat treatment, having made swords proffessionally for the last 18 years. What is the ideal hardness for armour? Blue, or harder? Blue-grey, or that getting too soft. - How do you avoid or minimise warpage? I have read about using cross-bracing to keep the plates in shape for quenching. Is this the way to go? - What pitfalls am I missing? (there are always some)

I've got a good reference library and found evidence of all the components of the full armour from well before 1372, but the BP effigy is the earliest that pulls them all together.The Romance of Alexander (finished by 1344)shows leg harness that could be fully articulated (though it is hard to tell as the details are ambiguous). But several carved panels from the church of St Nicholas, at Hugenot, France (dated by David Nicolle to 1350-1355)show full leg harness, with fans on the knees, doubled lames above and below the knee, and sabatons. Full arm harness is shown as early as 1349 on the tomb of Hugh Despenser, and hourglass gauntlets also appear on monumental brasses, for evample W. de Aldeburgh (c.1360) and commonly from 1380. Breastplate and faulds are more problematic, since most effigies show them covered so the design can only be surmised by the waisting appearing on the effigies. The earliest that clearly shows it is the silver panel in Pistoia Cathedral, Italy, from 1371 or 1376, which shows a breastplate with a central ridge (impossible to know if it was intended to have a back plate as well, since another panel shows a breastplate held by cross-straps at the back), and five faulds at the front. The date of 1372 is a bit arbitrary. It was either 1372 or 1376 (I can't remember just now) that John Lyon, thane of Glamis, was knighted. I am modelling my character, and armour, on a relative he might have had in this period. So whether it is 1372, 1376, or 1380, is not so important.

Yes, the breast and backplate dilemma is a tricky one. I have as yet not found evidence of a backplate in use in the 14th century, and plenty of examples of breastplates worn without backs, such as the Pistoia Cathedral alterpiece, right into the late 14th century. The earliest good proof of a metal breastplate in the Germanic areas seems to be from the effigy of Beringer von Berlichingen, died 1377.The hourglass gauntlets I totally agree with. I had a good look through my image archive and came up with plenty of full limb armour in the 1360's as you said, although only with the small round fan and without any indication that the lames were articulated on rivets, but some evidence that they still used a cloth backing type articulation, at least where more than one lame was being used above or below the couter. That is, an articulation similar to that used on the lames of a fauld. See the effigy of W. de Aldeburgh, Aldeborough, Yorks c.1360. I don't know if a date has been assigned to the tomb of Hugh Despenser. The date of 1349 is the date of his death. As for the plate leg armour with poleyns articulated on rivets with a lame above and below, I have as yet no evidence of it's adoption in England until well after 1372. If the date is not so critical, I would certainly think that moving it to 1376-1380 would be much safer for justifying the articulation of the poleyn. I don't agree with your use of the Romance of Alexander (Bodelian MS 264) to suggest anything like full plate leg armour with poleyns articulated on rivets. I see cloth knee padding with a poleyn strapped or riveted (over or onto) it. The St Nicholas reliefs are certainly an interesting, and totally unique example, of some very complex knee articulation. I really don't know what to make of them. I have as yet not read that they may have been reworked later, which was not unknown. This work of art is just too isolated an example that it would be dangerous to use it to justify poleyn articulation on rivets for an English night, especially when we just don't see that on effigies until well after the date suggested for the St Nicholas examples.

I have read somewhere that one of the vambraces from Churburg is made to articluate on leathers. The difficulty is in knowing when rivet articulation started being common. In the Germanic lands it seems to me to have not been until after 1380 or so for leg armour. At that time we see the adoptation of North Italian made leg and arm armour.The figure you metion on the Pistoia alterpiece certainly does appear to have some form of back armour. Looking at the other figures, it could be part of a leather cuirass or a corazzina. It certainly isn't very clear. The backplate is a real problem. You are unlikely to be able to provide proof for it. Many have already looked. What you do it up to you. If you cover it with a jupon, you will certainly look the part of an English knight. The splint cuisse on the Romance of Alexander miniature is a good indication that the colouring is not perfect. Splints seem to have been either internal or alternating external and internal. The former would show no metal, the latter would show only the metal strips, the rest would be cloth or leather. The fact that the cuisse we see on p74 is all blue, even below and between the splints, which appear to be externally mounted, shows that the artist most likely made an error. As it is, you are certanly correct that they look to be wearing full plate leg armour. We know that full greaves were around quite early in the 14th century, some possibly made of metal, others of leather. Metal poleyns were the norm, and splint cuisses, possibly even plate cuisses were also known from before 1350. So the elements are all there, but the articulation is not. It looks to me from what I have seen, that the poleyn was often attached to the cuisse or to a cloth backing worn over the knee joint. The schynbald or greave was most likely seperate as they are often shown worn under the cloth that is worn over the knee. This can be seen on Bodelian MS 264 fol.43v. I know I'm being a thorn in your side, but I like to see people base their armour on a sound foundation. I guess you have three choices regarding the leg armour. Change to a later date, find examples of English effigies that clearly exhibit what looks like rivet articulated leg armour, or get yourself some leg armour correct for the earlier date. I have no idea what you could justify for back protection to go with a breastplate, other than just mail. Erik [ 05-06-2004: Message edited by: Erik Schmidt ]

I don't mind at all, I'm learning a lot from this. If I'm looking at my armour being in the 1376-1380 period, it sounds like I'm on safe ground with the details I'm planning. Since the Romance is about 40 years earlier than this, it is largely academic, I've just been trying to find out when all the components and details originated, to be sure it is justifiable for my chosen period. I hadn't known about the German backplate from 1377, so that is all good to learn. Do you have an English-language source for pictures of it? Regarding the Black Prince effigy. The elbows have articulating rivets visible, but none on the knees. Does this suggest the knee units might have been on leathers rather than articulated on rivets? Or could it be an artistic thing, as the legs of the effigy seem slightly less detailed to me than the torso and arms, maybe components made by a different workshop?

The German effigy from 1377 shows a breastplate, not a backplate. I don't have any references for a backplate. If you want to look at it anyway, it is pictured in the German book; Bauch, Kurt (1976) Das mittelalterliche Grabbild: figürliche Grabmäler des 11. bis 15. Jahrhunderts in Europa, Berlin [u.a.]: de Gruyter. I don't know of any English language sources, but it's on line at; http://www.bildindex.de/ Look under 'Orte', then find 'Schöntal an der Jagst'.If the elbows on the BP effigy show the articulation rivets, that's great. At least you know they used them by then. I have no idea why they were not shown on the knees. It could be beacuse they had used leathers, who knows. The sourcing of components from different workshops is certainly a possibility, although less likly given his status. I get the feeling that those who could afford it would wear matching armour pieces, often ordered at the same time from the same workshop. That's certainly the case with the later suits and possibly also with some components of the Churburg armour from the 14th century. Erik

Hey Mark, 'Schöntal' and 'Schöntal an der Jagst' are the same place. The ending just refers to the river that it is near, and such endings are often used when more than one place with the same name exists. Unfortunately the endings are not used consistently, which can make it hard when you have a reference to a place name with five to choose from on the map.Anyway, back to Beringer. You will find the effigy if you follow the subfolders; Sakralbau - Kloster - Nebengebäude - Kreuzgang. There are several effigies there. To go directly to Beringer go here; http://www.bildindex.de/fotos/mi/089/55/a/MI08955j10a.jpg Erik

I think the Black Prince's effigy presents one of the more convinving pictoral representaions of a backplate. Although it is not visible, when viewed in profile it had a very rounded form and supports his entire weight. Erik: Based on my reading of Scalini's work on Churburg he strongly suggests that the 14th century armour at Churburg was not purchased "en suite" but rather purchased over time. He backed this up with evidence from castle records of purchases. This does not mean that nobody purchased armour as a suit but at least some people of their rank must have bougt it piecemeal.
