Editing Crossbow (section)

==Types of Crossbows==
As a general note, crossbows are not ballistae, despite their visual similarity. Unlike crossbows which store energy in a set of arms which are bent back, ballistae store energy in twisted rope that has a wooden beam pushed into it which is then twisted back farther before firing to store energy. That said, some ballistae are discussed here until a proper "[[Siege Weapon|siege]]" article is consolidated.

*'''Gastraphetes''': An early Greek crossbow, the gastraphetes, or "belly bow", was cocked by resting the stomach on the bolt rest of the stock (which contained a sliding plank attached to the drawstring) and pushing down so that more energy can be stored then an archer could provide. The gastraphetes worked slightly different from the classic crossbow, in that its arrow slot was two-piece, with the sliding inner plank attached to the drawstring. Thus, rather than drawing back the crossbow, you readied it by slamming it into the ground until the trigger caught onto a latch. While impressive, it was restricted to hip fire, was fired with a button-like trigger, and was more of a man-portable siege weapon. A larger winch-spanned, tripod-mounted version, the oxybeles, was in use as a stationary artillery weapon before being replaced by the ballista (which used less fragile torsion rope rather than wooden prods).

* '''Polybolos''': Roughly meaning “multi-bolt thrower” in Greek and also known as a "repeating ballista," the Polybolos more often resembles a big crossbow than a ballista since the arms are fixed to the "stock" and don't twist around to fire it, though some versions do use arms wedged into tense bundles of twisted ropes like regular ballistae. The repeating ballista was fired by turning a wheel connected to a chain drive forward to cock it, then turning it the other way to load it again from a hopper on top of the stock and fire it. Assuming the operator is standing on the left side of the weapon, turning the wheel at the back of the crossbow counterclockwise pushed a sliding plank called the mensa (like that from the gastrophetes/oxybeles) forward. Once driven forward sufficiently, the latch claws at the back of the plank are triggered by a forward-placed lug into holding the drawstring in place. Then, turning the wheel clockwise drew the drawstring back as the plank slides backwards. At the same time, the motion of the plank drives a screw threaded pole (in contact with the plank by a block with a sliding nut) to rotate and load a bolt via a built-in notch on the rod) onto the body of the plank from the hopper on top. Pulling the wheel back to the very end will bump the latch against another lug that triggers the latch into releasing the drawstring and firing the bolt.

* '''Chinese "Nu" crossbow''': the Chinese version of the crossbow is noticeably different from the European crossbow which had a power stroke (drawing span) of about 7 inches, used a rolling nut latch held in place by a sear pushed by a long horizontal lever-like trigger mounted in the middle of the stock, used short and heavy bolts, and used prods (bow pieces) made from simple wood, composite, and later metal. In contrast, the Chinese crossbow had a power stroke of about 21 inches, used a complicated two-piece vertical trigger at the very back of the stock (held together by tension and two pins at the very end of the stock) inside a pistol grip mount, fired full length arrows, and used wood or composite prods (often salvaged from recurve bows and constructed for conscripts to use ''en masse'' instead of drilling archery skills into them). Due to the longer power stroke, the bolts fired by the Chinese bows (usually with draw weights of 380 lbs) were launched with comparable performance to an average European windlass crossbow (with a draw weight of 1,500 lbs), assuming all other factors are equal. However, the Chinese crossbows themselves were rather large, cumbersome, and had to be reloaded with just stirrup rings, belt hooks, and/or gloves.

* '''Chu-Ko-Nu''': literally meaning “Zhuge’s Crossbow;" classical legend associated it with a Chinese strategist named Zhuge Liang (2nd Century AD). Alternatively known as the "Lian Nu" (repeating crossbow), it's also known as the "Chinese repeating crossbow" and is one of the more common types of specialty crossbows seen in fiction. In reality, it was invented during the Warring States Period (4th Century BC) in the State of Chu. The term "repeating crossbow" brings to mind some bastard combination of Assault rifle and crossbow, which it kinda is and is not. Without doubt, this thing could fire quickly; trained soldiers could loose ten bolts in fifteen seconds before having to reload. Chu-ko-nus were limited to hip fire, giving you almost [[ork]]-tier accuracy in exchange for an appreciable volume of fire. In layman's terms, it's the same as being restricted to hip-firing a pump action shotgun with the trigger permanently welded in the fire position. Additionally because you were pulling the string back one-handed, the bolts had a lot less penetration power than those of a regular crossbow. However, the bolts (which fell down onto the stock from a hopper mounted on top) were often poisoned to make up for that (as seen with the [[Drow]], who make use of the weapon extensively). Now, no matter how potent the poison on your bolt is, you're not gonna kill a man instantly with a scratch. On the battlefield, however, causing enough pain to make a person go into shock is as good as killing them outright, and poison can deliver pain in spades. The downside was you had next to no luck piercing good quality armor or even thick leather clothing. Historically there are two known designs for the repeating crossbow:
**The most common example is associated with the Chinese Ming Dynasty and their allies in Joseon Korea. Mechanically, it consisted of a stock, mounting the prods and the lever (which attaches to the moving box magazine), that the user secured on their hip with the bowstring sliding through a slit on each side of the sliding magazine/bolt rest. By pushing and then pulling the lever that secures the magazine to the stock, the user catches bowstring on a notch at the tail of the slits in the magazine’s back end while loading the bolt by gravity onto the bolt rest. Once the lever is fully compressed down, a sliding lug nut at the base of the magazine pushes the string up off the notches and propels the bolt out. However, because of the mechanism's design, the swinging action that pulled the string back also fired the bolt at the same time while the magazine is built on top of the bow. Due to that, you could not pull the string back and then aim.
**An earlier version from the State of Chu used a pumping lever (which had a handle loosely attached by chord) at the back and a pistol grip under the stock at the front where the prods are attached (held by the user in a manner similar to drawing a regular bow). On top of the stock was a fixed double magazine. Inside the stock, a sliding lever held a complicated trigger assembly composed of a metal sear and latch (the entire thing being shaped like a crab's claw arm). When pushed forward by the lever, the trigger locks after coming into contact with the taunt drawstring, with the lever's internal grooves and the sear holding it in place by friction and tension. Upon being almost fully pulled back, the double magazines drop two bolts onto two firing slits on either side of the trigger inside the crossbow. Upon the lever being fully pulled back, the metal sear comes into contact with a round bar holding the sliding lever in place and pushed the latch into releasing the drawstring to propel the loaded bolts. Compared to the Ming Dynasty & Joseon Dynasty's equivalent of an overhand lever action shotgun, the Chu State's version was more akin to a double shot pump-action shotgun. While somewhat more advanced than the Ming Dynasty's model, it was even weaker than the latter model while also using a complicated mechanism that couldn't be reproduced quickly for home defense or militias.

* '''Balestra Veloce/Löffelholz Armbrust crossbows''': First mentioned in Leonardo Da Vinci's Codex Atlanticus (1478 to 1519) and Martin Löffelholz's Codex Löffelholz (1505), both versions of the said lever-action design (which differ mainly by the arrangement of the trigger, latch, and sear mechanism) used a stock consisting of two wood and metal pieces on top of each other and hinged at the head of the crossbow. By unlocking a catch on the stock, the user can then swing forward the bottom half of the stock to extend a latch housed in a sliding plank (like that on the gastraphetes) forward to catch the drawstring. Once the drawstring is caught, the stock is then closed, locking the stock back together and bringing the latch (which is held firm by a spring-loaded sear) back into contact with the trigger on the lower half of the stock. The user can then load the bolt and pull the trigger to compress the sear, letting the rolling nut release the crossbow string. Whether the German or Italian version came first is unclear, though the rapid fire crossbow pages in the Codex Atlanticus are dated back to 1485. Either codex's blueprints can be found online via an online archive created by "The Visual Agency" media company or a pdf scan hosted by Krakow's Jagiellonian Library respectively. While reconstructed models have been made firing and reloading more rapidly than the mainstream and historical goat's foot lever crossbows (to say nothing being much quicker than hand-spanning or using cranequins), there’s no proof that the designs were ever constructed or used in historic European arsenals and was never mass produced due to possibly three reasons.
** First, the amount of expert craftsmanship to theoretically make it and the extensive training to use it was cost prohibitive for a relatively complicated and delicately structured weapon. This meant that it was likely more of a special luxury weapon that only wealthy people could afford rather than a mass-produced weapon for conscripts (the same reason why breech loading rifles existed since the 16th Century for noble hunters but didn't replace muzzle-loading smoothbore muskets in mass use for militaries until the 1840's by which time the mechanical, chemical and material technology had become far in advance of the Renaissance).
** Second, while quicker than spanning a crossbow with a goat's foot or gaffe lever, the draw weight for the Löffelholz Armbrust and Balestra Veloce is reduced to a mere average of 220-300 lbs respectively. Being half of the maximum draw weight of gaffe and goat's foot lever crossbows, this meant weaker penetration and shorter ranges. In other words, the lever action crossbow achieves a speed slightly faster than a gaffe/goat's foot lever bow but its draw weight has been reduced to the same level used by their Glove-and-Stirrup ancestors over half a millennia before their invention. This was likely to make the lever-action crossbow more easily rearmed without being too strong to either break the trigger lock or prevent you from operating the levers with your hands.
** Third, the introduction of gunpowder weapons alongside the volley fire from massed pike and shot square formations occurred during the Renaissance. Since these crossbows were developed right when gunpowder took over, this meant these lever-action crossbows already went obsolete the same way that heavy plate-armored cavalry and longbow archers did. Hence, this is why these crossbow types (as well as other related [[Combi-weapon|combination]] specimens preserved at Vienna's Kunsthistorisches and New York City’s Metropolitan museums) were usually hunting or city militia pieces rather than military arsenal pieces. Only in the mid-2010’s were historians and arbalists able to build working reconstructions. Funny enough though, the Uruk-Hai crossbows from The Lord of the Rings films, constructed by visual designer John Howe, actually used the mechanism (but upsized and made spikier) designed in the Codex Löffelholz (as shown by the Weta Workshop behind-the-scenes clips in the extended edition of ''The Two Towers'').

* '''Latch/Latchet Crossbow''': A light lever-action crossbow popular with Scottish border raiders called Reivers in the 1600's to 1700's, it worked via swinging an internal metal lever forward from the top to push a sliding latch forward to secure the drawstring after unlocking the spring-loaded catch. The user then pushed the lever backwards into the body to arm the bow before loading and shooting. Popular to the Scottish in the region for home defense and raiding as they were small, easy to use, easy to make, very quiet compared to the more finicky wheel-lock pistol, had a decent draw weight of about 250 lbs, and took only 10 seconds to reload. Their downside was their short range, very short power stroke, and being restricted to hip firing due to the trigger being a button on the top (a trade off to enable horsemen to fire one-handed from the saddle, though you could tuck it into your armpit and adjust to aiming over your thumb). Similarly designed crossbows have been found elsewhere but tended to be ballester crossbows used to fire bullets at game animals.

* '''Bed Crossbow''': A Chinese peculiarity, where multiple crossbows mounted on a static frame were combined to create an increased draw strength. A precursor to the compound crossbow.

*'''Bullet Crossbows''': Also referred to as pelletbows, stonebows, and ballesters, these were essentially the same as regular crossbows or similar to a slingshot in crossbow form, except they fired stone or lead shot instead of bolts. Usually used for recreational shooting and hunting small game animals.

*'''Crossbow pistol''': Small crossbows designed to be fired from one hand, with modernized versions commonly featuring a more modern pistol grip and trigger. While these did exist in the past, they were nowhere near as lethal as battlefield crossbows as the draw weights were far smaller.

*'''Arbalest''': After European armor improved with the development of steel plate, crossbows with wooden bow sections were just not cutting the mustard anymore. As such they began making that part out of steel. This meant that the bow could store more energy and launch a projectile farther and faster, significantly improving armor penetration but also greatly increasing the draw weight, often requiring various levers and cranking mechanisms to reset it.

*'''Slurbow:''' A crossbow with a cover over its barrel and a small gap used to draw its string back. Arguably influenced by the pistol, the slurbow was mostly used for firing unfeathered quarrels or darts.

*'''Sauterelle''': The last apparition of a crossbow-like weapon in a modern battlefield for frontline work. In WWI, soldiers had a problem: all the artillery that existed was big and unable to drop explosives accurately into a trench, especially at close range. And on the other hand, thrown hand grenades had the precision but too limited range. As an interim solution the French and British deployed a number of catapults that were designed to lob grenades. But the catapults had some draw backs in weight and portability, and the French were always just ITCHING to get out of the damn trenches and take the offensive. So while the mortars were still on the drawing board the French army invented the ''Arbalète sauterelle type A'' or just ''Sauterelle'' (grasshopper in French) to replace the Leach trench catapult and eventually the British started using it as well. In terms of design, it was basically a big crossbow built to lob grenades at around 150 yards distance. Worked decently enough but basically everybody knew it was an interim solution and later in the war they were replaced by small, two-man team infantry mortars that were just as easy to move around and use but had three or four time the range and a better rate of fire.

*'''Compound Crossbow''': the modern version of the crossbow, which is basically a modern compound bow (complete with pulleys, springs, and synthetic elastic materials)on a rifle stock. Many of these also come equipped with telescopic sights modified with cross-hairs that compensate for the effects of gravity, wind, elevation, and other factors that might affect a bolt's accuracy. They are primarily used for hunting, sport and (unusually) home defense in Britain since everything else has been banned. Also finds military special forces, espionage and law enforcement use by firing ziplines or grappling hooks, explosive, incendiary, poisoned or gas-releasing projectiles, or simply well made darts for a relatively silent kill. Most use conventional spanning mechanisms but some more recent exotic ones combine various technological concepts from past and present such as the Balestra Veloce's lever action system and the Chu-Ko-Nu’s top magazine, alongside modern optics, grips, and compound composite bow-pieces.
