For those that are wondering why this thread is locked, it is because even after a warning a lot of people still fancy themselves quite the comedian. We'd like to clarify that we don't mind a joke from time to time, but once a stream of identical jokes comes streaming in it rather detracts from discussion of the actual topic.

So in short, the thread is locked because people are too lazy to see if a joke already has been made and can't read sticky comments from mods asking to maybe not make the joke that already has been made a few dozen times.

Thank you.

Handed in by a man who worked at a power station in northern Israel, a Greek Fire grenade likely used in naval battles. Looks really cool too.

[–]musedav 168ポイント169ポイント  (3子コメント)

Woah, it's a greek fire grenade? The article says it was filled with naptha, but I had thought we still don't know how the greeks produced it.

[–]digitalwolverine 95ポイント96ポイント  (1子コメント)

There's been a lot of research done on the subject, and Naphtha is the current popular theory for Greek fire (it is a naturally occurring substance in the area). But, it's still just a theory.

[–]moriartyj 25ポイント26ポイント  (0子コメント)

Hasn't the recipe for Greek fire been lost to the ages? Wouldn't that be a spectacular find?

[–]Truthmobiles 558ポイント559ポイント  (13子コメント)

That was my first thought. Between the discovery of Greek fire or a lazy journalist, I would assume the latter.

[–]Cdnprogressive 454ポイント455ポイント  (29子コメント)

Right? I went in thinking "ancient grenade, cool" and then read "Greek fire" and thought well this can't be what it says it is because the Greek fire sitting inside the grenade is the real find here and any historian would jump right on it if this were true, so I don't know what to think about it.

I think it's saying that a normal "grenade" WOULD HAVE been filled with Greek fire. I would guess the seal has broken on this one and it's probably just filled with gunk now.

[–]LovecraftInDC 154ポイント155ポイント  (15子コメント)

There's still a good chance they could get some evidence of it from what's still in the canister. They've done this with some beer formulas, I know.

Try the Midas Touch, if they still brew it. It's a recovered Greek recipe thats really different.

They still make it. It's got a lot of grape must flavors. Kinda like a very malty wine. Oh, and I think they work with bioarchaeologists to recreate the recipes by analyzing residues in jars. My personal favorite is Etrusca. Ta Henket is also good.

Not exact, though - a lot of varietals used, for instance, don't exist any more.

Could they test for traces of compounds in the grenade or is that not possible?

[–]SeattleBattles 17ポイント18ポイント  (0子コメント)

I would think that nothing would be left after 1,000 years of exposure to the sea. They also may not have filled them until they were ready to use.

Hasn't the recipe for Greek fire been lost to the ages?

The Knights of St John used it in various forms at the Siege of Malta in 1565.

They called it "wildfire", and used it in grenade-type bombs and a flame-thrower type projector called a Trump. They had other various gunpowder type weapons (things similar to Chinese fire spears) and conventional cannons, along with some other improvised fire weapons. They used them to devastating effect to literally cook Jannisaries trying to scale the walls.

I thought greek fire was just crude oil

[–]multiple_iterations 261ポイント262ポイント  (19子コメント)

As I understand it, whatever formula it was, it was like napalm, would burn under water, and burned for an incredibly long time, virtually guaranteeing anything flammable would catch. But I have no sources, and I'd love to hear from someone much better informed.

It has been suggested that lime (calcium hydroxide) might have been one component. Once water is introduced, a great deal of heat is generated, possibly enough for autoignition of a hydrocarbon carrier such as naphtha.

[–]grubas 10ポイント11ポイント  (0子コメント)

It was a mixture of a bunch of things. Basically it was like napalm but with a few additions. Napalm can be crudely made by pretty much anyone. There are rumors that they had things that would react with water so it still burned, was intensely hot and other historians say that they used plants or plant matter that either is extinct or that we don't know how to process.

[–]Arcosim 20ポイント21ポイント  (2子コメント)

Can't be crude oil, crude oil is too thick and dense to be fired at 30+ feet using the cheirosiphon (Greek fire launcher). These were hand pumped and two men were able to operate them.

[–]adjust_madi 3ポイント4ポイント  (1子コメント)

So how did they fire a liquid steadily to a distance of 30f?

[–]Arcosim 10ポイント11ポイント  (0子コメント)

It was a siphoning mechanism. They pumped air into a compression chamber by hand and then when they had enough compressed air they opened a valve which released the compound pushed by the compressed air bellow it. This guy built a working replica.

[–]SerMerynTrance 31ポイント32ポイント  (4子コメント)

I don't get it. If a 13th century weapon was using Greek fire, how do we not have a written record of how to make it?

[–]AzekZero 98ポイント99ポイント  (1子コメント)

It was a state secret of Constantinople. The Roman state deliberately obfuscated the technology to keep it out of the hands of their enemies.

A user on r/askhistorians mentioned no one person had an understanding of the entire manufacturing process as a security measure. If true, this would've made it difficult for a rival state to reconstruct it even right after the demise of the empire.*

*I went back to the post I was referring to, there's no mention of this. If I read the above tidbit in a different place, I've been unable to find the source.

Due to its military value the recipe was probably closely-guarded; most likely rarely, if ever, committed to paper.

[–]evanbyrne 8ポイント9ポイント  (0子コメント)

The exact recipe will not be known unless they can find a sample which can be dated to the period, but there are plausible hypotheses. I wish people would Google before embarking on this comment train for the bazillionth time. It is not that mysterious guys!

Its just the recipe that has been lost. We know how to make similar end products, just not how THEY made the product. It would be like losing the Coca-Cola recipe and then finding a bottle of coke. Just because we have the end result doesn't mean we know the Coca-Cola secret recipe.

[–]Devildude4427 67ポイント68ポイント  (10子コメント)

Not quite. It would be like losing the Coca Cola recipe, and making something that refreshes us and tastes similar to the notes left behind, but we don't know how our replacement tastes comparatively. We have compounds that act similar to Greek fire, but we don't know what it was actually made of or how it burned. We just have notes on it.

[–]ilovepumpkin 9ポイント10ポイント  (0子コメント)

Heh, this means if we ever do figure out how to make Greek fire, that we may be left disappointed given what we have today.

Guarantee, with a mass spectrometer and time, the formula could be reverse engineered.

[–]Zuwxiv 8ポイント9ポイント  (8子コメント)

You have a glass that's 10% salt and 90% water.

  • Did I add 1 part salt to 9 parts water?

  • Or did I take salt water that was already 5% salt, and add extra salt?

[–]Thatlawnguy 34ポイント35ポイント  (7子コメント)

Bad analogy, at the end of the day your example only has 2 ingredients. Who cares where they come from. The 2 ingredients can be determined and the solution could be replicated.

[–]sidepart 22ポイント23ポイント  (5子コメント)

Different example related to music. We have the sheet music, but the composer never wrote down any tempo. ...so how did it really sound?

[–]Thatlawnguy 13ポイント14ポイント  (2子コメント)

A mass spectrometer couldn't tell you that.

[–]sidepart 22ポイント23ポイント  (0子コメント)

Hell nah, but in the same vein, a mass spectrometer can't tell you how long a cake was baked for. Or that to get the appropriate tenderness of the crumb, you have to combine the wet ingredients first and slowly add the dry ones. The point is that just knowing the ingredients isn't always enough.

The salt water thing I totally agree wasn't a great analogy. When you just have salt and water...doesn't exactly matter how you got there.

Isn't Napalm basically Greek Fire?

[–]SeattleBattles 23ポイント24ポイント  (0子コメント)

Napalm requires gasoline, and while the Byzantines had access to petroleum, there is no evidence they had developed that level of refining.

However, it is likely that Greek Fire involved petroleum and it was 'sticky' like napalm so the two are potentially similar.

Like SuperSamoset said, survivorship bias. They used the normal boring ones all the time, but would have taken care of the fancy decorative ones. It's the same reason you see lots of fancy ceremonial armor/weapons but comparitively few ordinary/boring ones survive to this day.

These things aren't that rare... Apparently they are found a lot in the middle East. My archeology prof does a lot of work in Jordan and talked about them a few weeks ago. The most likely hypothesis of what they are grenades/Greek fire, used for shisha, or other decorative pieces.

[–]reunitedsune 44ポイント45ポイント  (7子コメント)

How did these things ignite? Or did they throw them and try to hit the Greek fire with flaming arrows or something?

[–]Zuwxiv 75ポイント76ポイント  (4子コメント)

Interestingly, flaming arrows really don't work that well. Anything shot on a bow will quickly extinguish, unless you have a big and heavy fuel source on it. That reduces range.

Siege weapons could certainly use flaming projectiles, and while I'm not saying it's never been done, Hollywood certainly loves their flaming arrows more than ancient armies did.

Back to the point - a flaming wick would work well. Of course, like most ranged weapons, it's best to employ them en masse. I'm sure some might break open without igniting, and eventually be ignited by other means. But if you could have a wick, that would be ideal. I suppose it never hurts to coat your enemy in something sticky, irritating to the eyes, and flammable.

[–]hezdokwow 20ポイント21ポイント  (3子コメント)

Wait a minute, I distincly remember reading Julius Ceaser has archers dip the arrow heads of their bows into a type of mixture in order for them to stay burning as they shot?

[–]Zuwxiv 30ポイント31ポイント  (0子コメント)

There was some cases, yes! You could use a pitch-soaked rag, or things of the sort. It wasn't unknown to ancient armies, it was more the logistics of the issue. Fire arrows needed more equipment, care when firing, made arrows heavier, and reduced range and accuracy.

There are a number of Roman sources that reference it, and a quick review suggests that the authors weren't particularly unfamiliar with the strategy. It seems like the use was noteworthy, though. In other words: Rare, but not unknown.

It certainly happened in sieges. It's just that most times, allowing archers to fire more quickly at longer range and greater accuracy was more useful than a small fire here or there.

[–]Krihible 14ポイント15ポイント  (0子コメント)

Calling that a "crusader-era" hand grenade is somewhat bad. The Crusades occurred over several centuries and while it's not wrong, it is not particularly specific. Was it a grenade from the 1st crusade or the 5th? Military technology changed a lot during this time.

[–]colinroberts 25ポイント26ポイント  (0子コメント)

You can buy these things on the international antiquities market for like 100 - 200 EUR a piece, which is pennies compared to everything else. It's basically just like the shitty roman bronze coin on ebay of the antiquities market.

Fascinating stuff. I could see why a weapon like this would be effective in naval battles during that time period, especially considering the fact all the ships were made of wood. I mean, you throw a few of those at an enemy vessel and it could easily become engulfed in flames.
