That's it.



Rule 5- No baiting or sealioning or promoting an agenda.

I'm not much of a fan of 'inflation calculators.'

According to most of them, $1 million in 1960 is $10 million today. But if you look at the actual prices, it makes no sense. $1 million in 1960 would buy two mansions, a fleet of cars, a nice boat, and you'd have enough left over to invest and have an income for several lifetimes.

Where did that 15 billion number come from?

Diocles' lifetime winnings, as recorded in Roman inscription CIL 6.10048, totalled 35,863,120 sesterces (HS) over a working life of 24 years. From this, he would have been paid an unknown sum by his management team, or his owners; his status as slave or free is not certain, nor is the likely amount of his total share.

Still a lot obviously, but where did that factor of 10-100 come from?

You probably shouldn't compare the price of bread then vs the price of bread now. It's $3 in the store, but that's after decades of developing efficient methods to produce bread in gigantic quantities, which brings the consumer price down.

An artisan loaf of bread made fresh by a baker near to me costs closer to $9, for example. This would be closer to the way they made bread at the time, but even now we have modern efficiencies and easier access to ingredients.

Even calculating based on the silver content when sestertius is 2.5g silver gives 90M grams of 90 metric tons. Each gram is valued around $1 so that's a 90M USD there.

I initially saw that number on a Facebook post and when I checked the source [1] it also mentioned the 15 billion figure so I went with it. Looking at it closely, the author did some "creative" math to get that number

His total take home amounted to five times the earnings of the highest paid provincial governors over a similar period—enough to provide grain for the entire city of Rome for one year, or to pay all the ordinary soldiers of the Roman Army at the height of its imperial reach for a fifth of a year. By today’s standards that last figure, assuming the apt comparison is what it takes to pay the wages of the American armed forces for the same period, would cash out to about $15 billion

Good catch, I should read the sources better and don't trust the Facebook (especially the Facebook)

[–] [email protected] 2 points 48 minutes ago

You have to do some extraordinary mental gymnastics to expect paying for all soldiers in the roman empire is comparable to paying for all soldiers in the US.

Do these figures include earnings from garum endorsements?

Sesterius "A loaf of bread cost roughly half a sestertius", where bread now costs about 3 USD, so that's ~ 24 million USD

Could you explain this math? If 0.5 Sestertius = 3 USD, we have a factor of 6. So then 35,863,120 Serterces should be 215,178,720 USD? What am I missing?

[–] [email protected] 1 points 2 hours ago (1 children)

35,863,120 sesterces = (times by 2) 71,726,240 loafs of bread = (divide by 3) 23,908,746 USD

Isn't that right?

[–] [email protected] 2 points 2 hours ago* (last edited 2 hours ago) (1 children)

no, you are dividing loaves of bread by 3 to get USD, that would only be right if a loaf cost 1/3 of a dollar.

The sequence should be money in Sestertius / (Sestertius per loaf) = loaves
loaves * (USD per loaf) = money in USD

oh, doy! blinded by the numbers, fixed now

Let me know if you spot any more goofs

I'd also be interested how this salary compares to salaries of other jobs. It doesn't really matter if that number is correct if also a janitor earned close to that.

[–] [email protected] 5 points 4 hours ago* (last edited 4 hours ago) (1 children)

From the wiki link above:

... soldiers of the Rhine army who rose against Tiberius.... demanded to be paid a denarius a day, and they got it.[3]

One Sistertius is worth 1/4 of a Denarius, and 1/2 a Sisterius can buy a loaf of bread.

So 1 Denarius a day = 4 Sisterius = 8 loaves of bread a day

If we assume 3 USD is the price of a loaf of bread now, then these soldiers were being paid 24 dollars a day. Seems pretty low, but I guess bread was maybe more expensive back then?

Soldiers now make around 60 USD a day (random googling), so we're dealing with a factor of 3 error which doesn't seem so bad

[–] [email protected] 3 points 3 hours ago* (last edited 3 hours ago)

AFAIK bread was quite a bit more expensive in the past, since baking involved getting up hours in advance to start a fire inside the massive earthen oven, not to mention that all the other parts of making flour were also way more difficult than they are now..

I think it might be comparable to meat these days? Something that everyone eats, but at the same time most people on some level realize that it's actually pretty fucking expensive and they should eat less of it, but it's just so normalized and tastes good so they just keep eating it every day.

(And for reference meat in the past would have been much more of a luxury, not in that people were vegetarians or anything but they'd just have less meat in every meal and they wouldn't turn their nose at organs and "low quality" stuff like we do.)
