It seems like a lot of crossbow discussion focuses on late medieval composite and steel crossbows, but what about earlier ones like the self bow crossbows used by Crusaders? I know these were lighter than the later crossbows due to the lack of spanning devices, but did they have significantly larger prods? It seems like a larger prod could have given even simple self bows incredible power.

I'd be interested to see some contemporary depictions of self crossbows and hear about their battlefield uses and crossbow units before the Hundred Years War if anybody has information on them.

Thanks

P.S. I did use the search function, but couldn't find very much on self bows specifically, sorry if the topic has already been covered.

The Real Fighting Stuff by Tobias Capwell pictures two crossbows that may be of interest, in that both have, or appear to have, wooden prods. I'm without scanner at the moment, so I can't . . . no, wait. My hard drive to the rescue! I do have pictures.

The first (p15) has what appears to be a single piece of yew for the prod, left knotted and rough. The author speculates, based on the characteristics of the prod, that its manufacture may have been as early as the 14th century.

The second (p25) is later, circa 1480 according to the text.

Aaaaand that's about all the text has to offer.

Anyway, the first may support the idea of a wide prod. Or maybe it's just a really skinny tiller. Both prods are pretty thick, though.

Towards the end of the 12th century there was a considerable innovation in crossbow design with the addition of the foot stirrup, roller nut and composite prods. By the 13th century crossbows had there classic design. It seems that the crossbows the crusaders were using and bringing to the middle east had composite prods. Though they all seem to have been spanned using foot stirrups of either 1 or 2 foot design and a belt hook.

But to answer the other part of your question. Yes the prods on the earlier self bows were much longer though the draw length doesn't seem to be much bigger. Wood prods will need to be longer than composite or metal prods to deal with the stresses. While no draw weights were listed in Josef Alms book on crossbows the heavier wood crossbows required both feet to span. the feet were placed on the prod on either side of the tiller (body). the bowman grabs the string and then rocks back using the leg muscles to span the bow.

All wood crossbows seem to have been used in Norway to hunt whales for a long time possibly till the late 1800s.

From Josephs Alms "European Crossbows: A survey by Josef Alm"
Norwegian all wood crossbow
Bow 91cm long, 4cm across, 3.5cm thick in the middle
tiller (body) 81cm long
Draw Length 29.5cm


Its not the length of the prod that would make it more efficient but the draw length. While I'm not an expert on crossbows it seems that crossbows traditionally favor raw strength over efficiency.

I'm interested on this subject, too.


There is a bas-relief from Puy, France, depicting two crossbows in a hunting scene, from the Late Roman empire. A drawing from a XIX century book is the only source, I don't know any modern photographs or drawings on this piece. It seems to have a nut...

Also, some crosbow nuts made from bone have been found in Roman contexts, but I cannot be more precise now on this (give me a couple of days to check it )

I think I had a picture at some point of a fesco/mosaic of a Roman who looked alot like Jesus hold a handheld (no stock) crossbow much like the one Iagoba posted...
Anyone else know it?

Our favourite norwegian source, the Kingsmirror(1250) states that it is "Also a good thing to have a horn-bow or weak crossbow that can be reloaded on horseback"
these would be small crossbows with wooden or horn-reinforced prods.

The idea of horn/wood composite bows where adopted by the romans from the peoples on their eastern frontier, and used by roman archers and cavalry. Frankish manuscripts from the 800s show recurved composite bows; Most likely they fell from use as as the extra performance was not considered worth the extra time to make one, compared with a stick or two-wood composite bow. There are still depictions of static recurves in high medevial manuscripts like Maciowski, though.

My professor told my in my Medieval Warfare class that the glues in the composite bow didn't hold up as well in western climates because damper air, hence its popularity on the steppes but its general absence in western Europe. If the Franks used them, did they somehow overcome this problem, or were they only used briefly? Or is this initial assumption incorrect?

Related to the use of composite bows (as bow or crosbow bow -I hope that's clear -)

Many Spanish Beatos (silos, Osma, Liebana...)and Bibles (Leon...) from around X-XI centuries show recurved bows. They may be composite:





A more explicit Cordobese text from the year 961 explains that in June, the horns of the goats and deer were recollected to make bows. They are frecuent in the Islamic art of the Peninsula (if you don't want to look for it: there is one archer in each corner):



The Liber ad honorem Augusti also shows plenty of them , but it's more "modern"

From the XII century the bow loses popularity and it's hard to find any mention at all of it: the crossbow was much more popular, and more represented in art.

Going back to the topic (early crossbows) I'd like to share the earliest image of this weapon in the Iberian peninsula (and perhaps of Europe):



You can see here bigger

That is the "Four Riders" scene from the Beato de Osma, dated in 1085. Perhaps is this one which Sam Gordon Campbell has seen: it is quite simmilar to the Roman one. The white horse rider is the only of the four with a minbus (?). Perhaps that may explain the simmilarity with Jesus (althrough certain interpretations of this book support that this rider is, in fact, Jesus itself).

I hope all this looong post has been of interest

Depending of the breadth of interest here, there's an article here describing the use of primitive release mechanisms in relatively recent African and American crossbows:

http://www.diaspora.uiuc.edu/A-AAnewsletter/newsletter16.html

And a couple of articles describing the primitive crossbows still used in South China and Indochina until well into the 20th century:

http://www.atarn.org/chinese/yn_xbow/yn_xbow.htm

http://www.atarn.org/letters/ltr_jun99.htm

As well as one describing speculations on the nature of the primitive trigger mechanisms that led to the mechanism of the classic Chinese crossbow:

http://www.atarn.org/chinese/bjng_xbow/bjng_xbow.htm

Of course, if Norman and Crusader crossbows could be described as "early crossbows," then Chinese ones ought to be called "bloody early crossbows" out of their sheer antiquity....
