The history of Troyes written in wax

Starting in the 30's AD, the building of Augustobona began with land drainage. The programme probably began under the reigns of Tiberius (14-37 AD) and then Claudius (41-54 AD), reaching its peak during the Flavian period (around 60-85). The city declined towards the end of the 3^rd century.

During the excavation, around twenty latrines and wood lined wells, reused as waste pits, were found. These fragile constructions, perfectly preserved due to the permanent humidity of the soil, contained food remains. Coriander, oregano and grapes were some of the rich food products imported from the Mediterranean world. Around fifty wooden objects were discovered in the latrines and wells: a comb, a wooden box, maplewood spindle, wicker basketry, and especially spruce and fir tablets.

One of the most remarkable objects is a Gallo-Roman 1000 litre barrel. Preserved to a height of 1.3 m, with a diameter of nearly 1 m, it is formed of 19 staves (spruce and fir) encircled by hazelwood hoops. The barrel was reused as a well lining, thus permitting its perfect conservation. Fabricated around 47 BC, it must have originally been over 1.8 metres high. It was used to transport acetum—sour wine or vinegar—used in the preparation of posca, Roman soldiers' favourite drink, made from 1/10^th acetum and 9/10ths water. 
Is this one object sufficient to prove the temporary presence of a legion in Troyes, vector of Romanization under the Emperor Claudius (41-54)? 

In the Roman world, wax tablets were widely used for correspondence or official documents. Generally made from boxwood, these ten to twenty centimetres long plaques have a depressed surface into which a thin layer of tinted wax was poured, creating an infinitely erasable and renewable surface on which it was possible to write with a stylet. 
The plaques were usually joined together in groups of two or more. Though several frescos from the 1^st century in Pompeii illustrate their use, these wooden objects are rarely preserved. 
Except for two made from spruce, all the elements are made from fir, some from the same trunk. These tablets are attributed to the second half of the 1st century and two of them are precisely dated by dendrochronology to 50 and 51 AD. 
Some, which have surfaces with incisions in the wood that resemble writing, are in the course of study by epigraphists. Graffiti on the back of some tablets could indicate the contents or authors of the document.
 The 26 objects from Troyes constitute a unique corpus in France, which resembles the finds at the small Roman fort of Vindolanda in England.
