Antiquity Tuesday - Coinage and Brilliant Minds - February 13th

I've always wanted to write about the subject of coinage in D&D, but haven't had time to do the research until recently. And not half the research I wanted to do. 

But from what I have, I can lead with the chart from the e1 PHB:

If you are playing a game based on D&D, this chart should be familiar to you in some form or another. Two weeks ago, I wrote about what a Roman soldier would carry and got into the coin-based encumbrance system. That led to a follow-up post from Ian Borchardt on Mewe that he graciously allowed me to post here. And this morning, I spotted a post from Stephen Wendell about "Holmes on a Coin’s Weight", which covers a realistic treatment of the mass of coins. 

OSR style games really went out of their way to make a system that while idealized, is actually excellent enough to hold up for decades and decades. It's actually amazing. 

But what about Antiquity Tuesday?

One of my favorite historical personages is Diocletian. He lived from 242ish to 311ish and brought about the Crisis of the Third Century. Yes, the 3rd Century was chaotic enough that we don't know the exact years. Whole books exist about the Crisis of the Third Century, but one of the crises was the triple problems of coins, inflation, and prices. And Diocletian actually failed to fix it. But he tried. And it was a hell of a try. 

Just like in AD&D, he decided the issue could be resolved with a simplified system of just 5 coins. The system was based on a silver coin worth 100 denarii. There is some variability in these values and please forgive me, but I don't trust this table in name or values. Take it as a guideline: 

aureus 1,200 denarii 
argenteus  100 denarii

nummus (a silver-washed coin) 25 denarii 
bronze radiate 4 or 5 denarii 
copper laureate 2 denarii 

What is interesting about this order or valuation is that bronze appears as a valuable metal. Both brass and bronze are alloys of copper, and that meant that bronze age implements had an innate value due to the material that they were made of. 

When compared to the AD&D valuation, we still have five coins, but electrum and platinum appear on Mr. Gygax's list. Electrum is an alloy of silver and gold which would have been more valuable than just silver and platinum wasn't discovered by Europeans before the 1600s. They may have known about it but it wasn't described until it was discovered in the New World. 

What I find wonderful about these two lists is that both are meant to be simply used. And they are perfectly logical for the system each is attached to. 

Unfortunately, Diocletian was unable to resolve Roman's economic problems, which were many. After he reformed the coinage, he call back tons, literally tons of old coins and replaced them with new ones. The Romans understood market forces, a lack drove up prices, and a dearth dropped them. What they didn't get was the variable value of coins themselves. To a Roman, a coin was a coin, was a coin. 

I bought my first PBH for $9. Used. 
This replacement was priced $15 and
I actually paid $50ish. Uhh. Inflation.

Parallel to this, Romans understood the dangers of debasement which is why Diocletian replaced so many coins. And this was also the very reason that other emperors debased coins in secret. They knew it was playing with fire. And Diocletian believed he fixed it but he didn't call back nearly enough coins to fix a centuries-old problem. 

But this was not lost on Mr. Gygax, debased coins or washed coins show up a couple of times in modules like B2 Keep on the Borderlands. 

A possible explanation for this lack of vision on Diocletian and every other emperor who monkeyed with the coin system was the hands-off nature of minor transactions. Roman grew in both space and time. Diocletian was trying to fix hundreds of years of bad coins on top of not seeing the effects of how Romans used coins on a day-to-day basis. As regions were absorbed into the Empire, so was their coinage. Who cared if people bought bread with denarii-based coins or some old copper from a defeated enemy? A coin was a coin. Fixed and constant. 

He had no idea what a battle he was fighting. But Diocletian didn't accept the failure of logic or reason. He decided that the actual problem was the merchants. Those evil little price gougers were running up the prices. So he tried to put a stop to it. He penned the "Edictum de Pretiis Rerum Venalium" or "Edict Concerning the Sale Price of Goods" or when we are placing blame, "The Edict of Diocletian". 

This is one of those seminal works, like the Domesday Book. It is a list of maximum prices allowed for 1200 goods or services in denarii communes or "common coins". Unsurprisingly, it looks suspiciously similar to a gamer: 

Brilliant minds work alike. This is a totally workable system... except Diocletian had to abandon his because it simply didn't work in his world, unlike Mr. Gygax who built from the ground up. If only Diocletian could have wiped the slate clean, I bet his system would have worked as well as Mr. Gygax's. 

What is awesome about Diocletian's cataloging of items is it reveals how people in antiquity thought. We know the Romans like to have 8 soldiers together carrying 3 pilums or 3 caltrops. But when it came to quills, they wanted to have a set of 4 in a leather box. We also know that most wines were of the same value when fresh, but worth somewhat less as they age. What is notably missing from Diocletian's list is weapons. No one bought a weapon, they paid for the services of an armorer who made weapons. Oddly, sharpening a sword, an axe, and a spear appears under several different categories of services. There is a difference in the task depending on the object. 

It really is amazing that someone would think of such a system several different times for completely different purposes. For the Romans, it was life and death. For us, it's a game. 

Antiquity Tuesday - Guest Post by IAN BORCHARDT

This week, I would like to welcome my first guest poster, Ian Borchardt. I have annotated this post with some images for clarity. Also, my thoughts are in italics. I managed to keep my commentary to a minimum, which is also for clarity. This post came about as a MeWe response to last week's Antiquity Tuesday and Ian has graciously allowed me to use his response for the Blog. 

Thank you, Ian. And thank you readers. 

A legionary conturbium after the Marian reforms consists of eight soldiers, two slaves, and a mule. The items required to set up the camp were shared amongst the conturbium, which was the lowest indivisible group of Roman troops for that reason. Thus they were often assigned duties together. The two slaves and mule stayed at camp, so were often ignored in accounting for the components of a century. Thus you have the strange situation of a "100" only having 80 soldiers. The military slaves/servants (servus) made up the other 20 since they also had to be fed. Camp and the baggage therein was a pretty important part of military life, hopefully, kept separate from battles. Until you lost.

Unlike D&D the legionary didn't fight whilst carrying this load. The two advantages of the furca, or carrying pole, was that you could wear armour whilst using it to carry goods and that it could easily be dropped if you were ambushed en route so that you were unencumbered in a fight. And you could carry the three pilums along with it fairly easily.

Ian's Icon

The furca continued to be a very convenient way to carry baggage for a long time (cf my icon, for example). The alternatives tended to be large wicker baskets and porter's trunks, which are not readily shed and more often used for carrying heavy loads. Slinging loads were poles was pretty common.

Wonderful inventions, poles. Although not very useful in a dungeon, but then any sensible legionary would have left the bulk of his gear back in the camp before they went exploring a dungeon.

The loculus, or goatskin satchel, was made from a single goatskin because that was the only way to keep it pretty watertight (as far as the rain was concerned). They were not particularly large as a result. It generally held the few personal possessions of the legionary. This and the other gear of the sarcina were carried in baskets or nets slung from the furca. Including food supplies and tools. All readily discardable in an ambush.

Most legionary food was prepared normally, and locally sourced. Again supplies were delivered to the conturbium as a whole to be prepared for all of its members by its members. This was fairly standard for most armies up to the 18th Century. technically the locals, if neutral or friendly, were given scrip for any supplies that were "requisitioned," but the ability to redeem that scrip depended on the local tracators. Iron rations were never really a thing until the 17th Century when you could determine an army was thinking of going to war because cheese and sausage were suddenly impossible to get for love and money (food that could easily be eaten cold). Most military preserved rations still needed cooking, even if they had a longish shelf-life and could be easily be transported. For example, salted food needs to be soaked to remove a lot of the brine before being prepared.

Next week, I will be trying out a recipe for Roman Hardtack from Pass the Garum, a food history website. As the recipe only has 4 ingredients, hardtack was probably invented and reinvented a zillion times over as a way to preserve the wheat harvest for lean times. (Edit - this has been canceled due to my daughter's Birthday Party. We will properly have cake instead.)

I also base my encumbrance rules on the Roman legionary but tend to consider armour as the primary encumbering item for determining movement rate. The next question is asking what you are doing with your hands, which I often find to be a more useful question to ask when you are carrying stuff than the weight of a thing. 

In many regards this is similar to RQ1/2 method of measuring encumbrance in the amount of things. The last question is the weight of what is being carried, which is the strength requirement. Usually such loads are self-encumbering from step two: what is he doing with his hands? Strength really only comes into it when they are trying to lift a specific load.

And I much prefer using Constitution in these matters, not least because it is the characteristic most associated in my game with the Peasant Caste.

Ian has saved me a post on Old School Essentials encumbrance rules. OSE has an item based encumbrance system which trades mass and weight for an item/bundle system which is intuitive and easy to use.

Antiquity Tuesday - The Sarcina Revisited

Back in September of 2021, I wrote about the sarcina as an alternative to a backpack. It's a stick carried over the shoulder by a Roman legionary. The sarcina came into its own around 107 BC, when the statesman Gaius Marius pushed for a professional paid army for the Republic. And it's been around ever since. 

Marius's goal was to eliminate the dependency of the army on a baggage train. To this end, all carts, and wagons were eschewed except when absolutely necessary. The average Roman soldier didn't travel by horse, they walked and carried everything they needed on their backs. While the Marian Reforms meant to eliminate the baggage train, it did not eliminate horses and sometimes the troops used donkeys or mules for support. 

Being that every rule has an exception, there was the Legio X Equestris, or 10th Mounted Legion which did travel by horse. In a strange case of history rhyming without repeating, there exists the 10th Mountain Division. Based out of New York, the 10th specializes in mountain warfare and makes limited use of vehicles and equipment like artillery. Being specialized in moving troops and equipment without support places the 10th at the forefront of humanitarian deployments. 

While I'm revisiting the sarcina, I want to compare what a Roman soldier would carry to what a D&D character would have. 

A soldier would have his sandal-like boots, leg wraps, a tunic, a cloak, a scarf, lorica type armor, a gladius or short sword, a dagger, a shield, and a bag to carry it, a helmet, and possibly some darts or pilums or caltrops, plus his sarcina. For some reason, when it came to darts, pilums, wolves, and caltrops, they were carried in threes.  

From that list, we can remove all of the clothing which is normal and customary. That leaves the following list (with weights) for soldiers in combat: 

Shield 100 cns or 10 lbs
Lorica 200 cns or 20 lbs
Gladius 30 cns or 3 lbs
Dagger 10 cns or 1 lbs
Helmet 0 probably counted with the armor
Darts 10 each or 1 lbs
or Pilum 20 each or 2 lbs

D&D seems to get these weights correct most of the time. No one thing would have a standard weight as they would scale to the wearer. A lorica is typically 11 kg or 22 lbs, which almost matches the list. So a Roman soldier would be carrying about 37 or so pounds in a combat setting. Where D&D slides is in the armor types slowing the base rate of movement down. The Romans ability to move and to maneuver was pretty much the gold standard in antiquity until they met eastern forces like the Huns and Seleucids. Armor wasn't much of a factor in speed of movement. 

But this essay is about the carrying capacity of a sarcina. So what is in one? A lot: 

satchel 20 cns or 2 lbs
cloak bag 20 cns or 2 lbs
shield bag 30 cns or 3 lbs
spare tunic 10 cns or 1 lbs
a pot 10 cns or 1 lbs
a mess kit (called patera) 10 cns or 1 lbs
a bag with 3 days of food 60 cns or 6 lbs.
iron rations 
a bedroll 70 cns or 7 lbs
a pickaxe 100 cns or 10 lbs
a turf cutter 70 cns or 7 lbs
a saw 50 cns or 5 lbs
a sickle 10 cns or 1 lbs
3 wolves (a type of spike) 15 cns or 1.5 lbs
a basket 
a water container 20 cns or 2 lbs
tinder kit 10 cns or 1 lbs
toiletries 
personal effects 

Some of these items have an unclear weight or mass. A basket would have been wicker and those weigh next to nothing. Toiletries and personal effects were probably less than 50 cns or 5 lbs all combined.  It's attested that those with too many toiletries or personal effects were roundly mocked by hardcore soldiers. Before Marius, some soldiers had a slave (or if you prefer, a worker with a job and no pay) in tow just to rub, perfume and oil a soldier before and after combat.  

The iron rations were a lamentable and dubious item. Bucellatum, as the Romans called it was hardly edible. Losing a tooth to the biscuit was a common war wound. Soldiers were actually called bucellarii or "biscuit eaters". Let's call it 2 lbs. or 20 cns.  

There are a couple of standout items on that list. The bags were made of leather or hide and heavy. They provided some structure to the sarcina so they were also necessary. 

All told, without the mysterious items without weights, the average Legionary was packing 50 lbs or 500 cns in the sarcina plus the 37 pounds of weapons and armor. Surprisingly, that is in the realm of what modern soldier carries on a good to a great day. 

What is interesting about that list is what is missing. The Romans had a great road system with mile markers. They also knew the lay of their own land. This meant that they didn't remotely carry as much water as a modern soldier. So long as they weren't going the wrong direction, they knew where the next stream, spring or well was. In foreign lands, they would have scouts looking for such things. 

The other thing that is missing from the list is a tent. The Romans had 8 or 10 man tents called a contubernium. There is no way for a man to carry one. Basically, they would set up camp with what they had and if necessary move the tents to the camp later. 

That sounds pretty poor, but if you think about what the sarcina is, it provides a solution. It's a pole with 3 different bags, a tunic, and a cloak. Two of them put together could be cobbled into a makeshift tent using the cloaks, shields, and bags. A Roman shield at its smallest is 2 feet by 3 feet and could be as big as 3 by 4 feet. The bag is bigger than that so the shield fits. While I wouldn't want to sleep in the snow with such a ramshackle tent, it's doable in three seasons. 

Now looking at a typical D&D character, they should be carrying just as much as a Roman soldier, but in a backpack. And judging by my players, they often don't carry that much by half. The players never think to bring a pickaxe, a turf cutter, a shield bag, or any of the other stuff a real person would need. Some of them think a 10-foot pole is ungainly. 

What I find amusing is, a lump of 1600 cns worth of gold is only about the size of a couple of two-liter bottles of pop. "Soda", to you demi-humans. That would totally fit in a backpack, but your spine would scream. This is another case of needing some other method to move something. Neither a sarcina nor backpack would help much in moving that much coin. 

This isn't to drag down the idea of coins to pounds for encumbrance, it actually proves the system works. And reasonably well. The flaw is in the idea that treasures would be limited to gold coins. I think everyone has had that campaign where the party ignores copper pieces because they aren't worth enough to pick up. 

The other thing is the dubious nature of iron rations.

But those are essays for another day.
