​

Also, the formal aspect of accounting, with the reference from one account to another and the double entries to credit and to debit presents a system that is already almost perfect…

​

[the Florentine account book presents] undoubtedly the first germs of double entry records that will develop and improve over the course of the 14th and 15th centuries.

Orlandino the tanner from Santa Trinità no die dare [debit] £26 by mid-May, for buolongnini [cash] {credit} which we gave him in Bolongna for the San Brocoli fair. If late, [the interest] is at 4 denari per libra per month and, if he does not pay, Angiolino Bolongnini the tanner promised to pay us. Witnesses: Compangnio Avanelle and Bellacalza.

Pietro Santini, philologist and historian (1887)

since the laws determined the rules to be followed in the compilation and maintenance of commercial books, it is clear that the jurists from 1211 considered valid, for the judicial effects in commercial matters, a document written in [the spoken language].

And since these fragments have a very developed form, which cannot be believed to have been formed there and then, it is natural to hypothesise that the bank book written in [that language], as we have it in 1211, already existed in the twelfth century.

Between 1150 and 1400 Sweden was transformed from a society which was predominantly reliant on oral communication into a society which increasingly deployed writing. Latin, the traditional language of government and records, was gradually replaced by vernacular Swedish. The watershed moment in this process was the drafting of national and town laws in the 1350s, an event which established Swedish as the language of the judiciary and judicial records. From this period written documentation was gradually integrated into legal procedure.

​

Pragmatic Literacy argues that the Crown, the expanding bureaucracy, the editing of the laws in Swedish, and the laws' demands for written documentation in everyday transactions were the main driving forces behind the development in medieval Sweden of lay literacy for practical purposes.

  • While I fully sympathise with this new approach to accounting history, I also believe that form and procedure are not completely devoid of significance and should not be entirely overlooked.

Raymond de Roover (1956)�defining double entry

  • A necessary prerequisite is that all transactions be recorded twice, once on the debit and once on the credit side.
  • This principle also involves the existence of an integrated system of accounts, both real and nominal, so that the

(1) books will balance in the end,

(2) record changes in the owner's equity and

(3) permit the determination of profit or loss.

Medieval bookkeepers often did queer things.

Perhaps they had good reasons for doing what they did,

but we no longer understand their practices

because we have a different point of view

and accounting has progressed since the Middle Ages

This is WHY the definition of DEB used by accounting historians conflates bookkeeping and accounting – doing so allows them to be Whiggish and focus on financial statements.

Whiggish History

Whiggish history views history as inevitable progress and improvement.

It sees the present and looks for signs of progress towards it in the past.

It is often adopted in response to a lack of knowledge and understanding of the context, surrounding evidence, action, or practice located in the past.
