The Project

Lexicon Leponticum (LexLep) is a web-based, interactive platform based on the MediaWiki open source application. The aim of LexLep is to provide an edition of the Cisalpine Celtic epigraphic corpus and an interactive online etymological dictionary of the Lepontic and Cisalpine Gaulish languages that is freely accessible for all users.

LexLep was created in the project P21706 "An interactive online etymological dictionary of Lepontic", funded by FWFFonds zur Förderung der wissenschaftlichen Forschung, the Austrian Science Fund, and directed by David Stifter.

Project history and objectives

The project started with two distinctive objectives:

  1. to design a web-based interactive frame-work program to host etymological dictionaries and lexicons of Indo-Europaean and other languages;
  2. to construct an etymological dictionary of the Lepontic language entitled Lexicon Leponticum (LexLep).

Combined in a single project, the results of LexLep present both scholarly and technological innovations.

In the experimental phase 1 of the project, Sept. 1, 2009–Feb. 12, 2010, the technical possibilities of the website were tested and the system MediaWiki was adapted to the requirements of the lexicon. The technical work was undertaken by Marcel Schwarz and Martin Braun. The conceptual groundwork, carried out in particular by Martin Braun, consisted mainly in developing the formal structures and routines that enable the automatised functions of the lexicon. The primary goal of Eva Lettner during this time was to compile a basic list of Lepontic inscriptions. At the end of phase 1, the experimental version of the lexicon was deleted.

At the beginning of phase 2 in February 2010, the system was recreated from scratch and the basic data about the archaeological objects carrying the inscriptions, the inscriptions themselves, and the dictionary headwords was entered in the database. Against initial expectations, technical questions still cropped up, and Martin Braun had to constantly apply his ingenuity to refining and advancing the technical backbones of the site. With the start of 2011, two new colleagues joined the project team, Mag. Michela Vignoli and Chiara Francesca Dezi, and two other colleagues added further support (Anna Adaktylos from Jan. 24–Feb. 28; Mag. Corinna Scheungraber from May–June); Eva Lettner left the project.

All objects had been entered into the database by the end of July 2010. Entering the inscriptions was finished in February 2011, under the responsibility of Martin Braun. Pages for the words were set up by Michela Vignoli, and filled in by herself and David Stifter. Chiara Dezi was in charge of filling the bibliography, and of adding further support in adding content to the site. Finally, Anna Adaktylos and Corinna Scheungraber checked the entries on the site for grammatical correctness. The entering of fundamental data to LexLep was finished by the end of June 2011, which also marked the official end of the initial project as funded by the FWF.

In March 2012, the Celtic Research Trust (Isle of Man) dedicated money to LexLep which opened the way for the continuation of phase 2 in July 2012. The main tasks were a revision and formal streamlining of the entire site – correcting errors and bringing the site into a formally consistent shape. This work was carried out by Michela Vignoli with the assistance of Martin Braun. In December 2012, Corinna Salomon added further support to the team. The inscription and word pages were revised and filled with up-to-date information, and received a user-friendly layout.

For phase 3 of the LexLep project (March 2020–May 2022), funding was acquired via an APART-fellowship from the Austrian Academy of Sciences. The two-year project CCeLL – Cisalpine Celtic Language and Literacy, led and conducted by Corinna Salomon, involved the re-examination and documentation of objects and inscriptions, and the updating of the pages with current, first-hand data. In the course of the project, the entries for 177 inscriptions and their associated pages were revised, completed and augmented by a commentary and full list of references. 75 documents and specimens of seven coin types in 18 repositories were examined, and new photographs of 61 documents were made available on LexLep. 32 inscriptions were added to the corpus.

Phase 4 commenced in June 2023. During the two-year Marie Skłodowska Curie fellowship CLINIAR - Celtic Language and Identity in Northern Italy and the Alpine Region at Maynooth University, with mentoring from David Stifter, Corinna Salomon will proceed with the revision of LexLep, including autopsies and the completion of the entries, as well as the expansion of the content of pages devoted to general information about the languages, script, history and archaeology of Celtic Northern Italy.

The envisaged adaptation of MediaWiki to the requirements of an interactive etymological lexicon has been satisfactorily achieved within the first iteration of the project. The system was continuously refined, and it is now able to achieve astonishing results. LexLep allows broad access to data about archaeological objects from culturally Celtic regions which bear inscriptions written in North Italic Script and/or containing Cisalpine Celtic language material, their find places and current locations, the in­scrip­tions themselves, and two dictionaries: a non-standardised dictionary of attested forms, and a standardised list of attested morphemes. In addition, a comprehensive bibliography is provided. The work on the content of LexLep is ongoing; the site is continuously updated with new inscriptions, references, data, and research results.
