They've now been renamed to TRANSACTION and LIABILITY

The last thing the team want to do is double-entry book-keeping :-)
The main aims of the project are:
1. How did the banks make their money? They couldn't charge interest
(the Church forbade the practice) and exchange rates seem to have been
the same between two currencies whichever direction the transaction
went. So were they using deposited money to trade in goods such as wool
and spices?
2. The Church had just started to use the banks to transfer money to and
from the Vatican. Did this sudden influx of substantial amounts of cash
give rise to an increase in trading all over Europe and thus provoke the
mini-Renaissance that only came to an end with the onset of the Black Death?
