Is the Admiral “unknown”(1) by the French Royal Chancery Registers?

This post is following the recent post by MAXIME GELLY-PERBELLINI with the same topic, but with a different research mater. Primary sources about the French royal admiralty for the medieval period are rather scarce and one looking for the Admiral of France will at first be very disappointed when looking in the French Royal Chancery Registers. Would it be? In fact the query “admiral” or “admiraldum” with all its declination in the HIMANIS search engine will only return one hit in French (JJ112, fol. 51v) and none in Latin, and for that one will have to take down the confidence level to 14 . For having gone through the printed inventories and through the registers manually, we can say that the Admiral of France is indeed present in the registers more than once. What is the reason for that?

Firstly, the word « admiral » was not part of the trained model. The recognizer have to read it by himself without previously knowing the word. Secondly, the word in itself is subject to reading error, for it contains a sequence of multiple similar downstrokes.

So, how to find the Admiral (or the Visdmiral) in the corpus? While looking in the complete list of indexed words I’ve found following word variation: adjural, annual, adminal and Anviril. The same problem occurs with the Visadmiral, as the computer read Visammal, Visauvel, Visanmal or Visaumal. Clearly, as the computer have to read the word without being previously trained with this word in particular, it is the sequence of “m”, “i” and “r” that causes the reading error. Below a quick summary of all the query that merit to find the foresail admiral. For consistence, all queries have been performed with 14 confidence level.

  • Admiral @14 > 1 hit
    • Adjural @ 14 > 34 hits
    • Annual @ 14 > 25 hits (majority of false hit)
    • Adminal @ 14 > 32 hits
    • Anviril @14 > 1 hit

The present version of HIMANIS did not use any dictionary for the word recognition, only a 5gram model. In future development, correcting the list of indexed words automatically by injecting linguistic reference will certainly help improve the recognition.

Having access to the list of indexed word certainly help to find the admiral, but it is not a panacea and does not resolve all the problems. With 4.000.000 words the complete list of indexed word is very difficult to handle on a basic computer..

One can also take benefit of the recal module. But for that you already need to have some good hits and explore how the computer read the word. That is how, in one case when the word “admiral” is separate in two parts ( “ad” and “val”), we found one more occurrence..

(1) The office of admiral of France is still today not very well known. See Mathieu Le Hunsec, « L’amiral, cet inconnu », Revue historique des armées [Online], 266 | 2012, Online since 06 September 2012, connection on 23 November 2018. URL :

  1. This is a general question rather than a comment. The Trésor des Chartes has a series of « registres » and some of them have been published, such as the registres covering the kingship of Philippe VI de Valois. These registres give a summary of every article of the Trésor. On the other hand, as far as I know, many registres, such as the one covering the kingship of Jean II le bon, has not been published. That is, they would not be available outside the National Archives. Have these registres been indexed by Himanis? Have they been scanned? If yes, they would be of great help for researchers if they were made accessible online.

    Thank you for your answers.

    1. A quick answer to your questions :
      Have these registers been indexed by Himanis? Have they been scanned? > Yes. All the registers from Philippe IV to Louis XI are in HIMANIS or in the IRHT BVMM (Virtual Library of Medieval Manuscripts).
      In a future iteration of HIMANIS all the summaries (published or not) from the National Archives will be added.
      All registers are also available through HIMANIS interface that offers a plain text search engine ( !
