       | A marvelous book comparing income and wealth across centuries is
       | _The Haves and the Have-Nots_ - A Brief and Idiosyncratic History
       | of Global Inequality by Branko Milanovic.
       | 
       | One way to compare wealth is to see how many people's labor an
       | individual could purchase. It differs across time and countries
       | (labor is cheap in India currently for example). This book is a
       | careful historic look by an economist - using evidence from
       | literature, history, etc. Branko uses a variety of ways to
       | compare individuals across history.

         | Executioners in the past would often be paid by the people they
         | were set to execute or their families. That payment included
         | the cost of taking care of the body afterwards, and in many
         | cases a fee for services as the alternative to an executioner
         | was usually much more grim and painful, whereas a good
         | executioner guaranteed a quicky and nearly painless death.
         | 
         | There's a fascinating video on YouTube by a channel called
         | Weird History with more on the topic:

           | Dollar analysis like 'how much did X cost in a pre-industrial
           | economy' is incredibly unsuitable for answering these kinds
           | of questions.
           | 
           | The answer is - most people weren't wage workers. Most people
           | didn't have money. Most people were subsistence peasants, and
           | they paid taxes, rent, and for many services in goods. What
           | money they had would usually go towards buying things they
           | couldn't make.
           | 
           | Most people wore homespun. Clothing a typical Roman peasant
           | family[1] would take ~3,000 hours of domestic labour a year,
           | most of it devoted to spinning flax. Being domestic labour,
           | done by the family, for the family, most of it, was, of
           | course, unpaid.

               | [Edit] - good answers below - thanks! But I think the

               | out elsewhere, a waterwheel is easy to construct and
               | doesn't have ongoing fuel costs. A steam engine requires
               | a reasonably well developed iron/steel working industry
               | (including skilled artisans), which in turn requires a
               | fair amount of iron ore and fuel to support smelting. The

               | fuel, or coal, which wasn't widely available in ancient
               | Greece, or easily transportable without a lot of effort.
               | Ancient Greek metallurgy was definitely not sophisticated
               | enough to build a steam train and as for for building a
               | railway 1) they could barely build graded roads and 2)
