Where did that 15 billion number come from?
Still a lot obviously, but where did that factor of 10-100 come from?
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
Good catch, I should read the sources better and don't trust the Facebook (especially the Facebook)
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.
Yeah that is an absolutely ridiculous bridge of assumptions and comparisons to walk across
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.
Yeah, but back then there wasn't "artisan bread" since it all was. Also no middle men or board members and ceo's and property costs and such. You were just one or two guys buying flour and salt and wood, making bread every day, that you sold every day.
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.
From the wiki link above:
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
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.
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?
35,863,120 sesterces = (times by 2) 71,726,240 loafs of bread = (divide by 3) 23,908,746 USD
Isn't that right?
Do these figures include earnings from garum endorsements?
This was if he had invested in Bitcoin right away.
They probably converted it using the BigMac index
Not sure but everywhere I look they say $15 billion
