DFHG Project

The Digital Fragmenta Historicorum Graecorum (DFHG) is a project directed by Monica Berti at the Alexander von Humboldt Chair of Digital Humanities at the University of Leipzig for producing the digital version of the five volumes of the Fragmenta Historicorum Graecorum (FHG) edited by Karl Müller in the 19th century.

The FHG consists of a survey of excerpts from many different sources pertaining to 636 ancient Greek fragmentary historians. Excluding the first volume, authors are chronologically distributed and cover a period of time from the 6th century BC through the 7th century CE. Fragments are numbered sequentially and arranged by works and book numbers, when these pieces of information are available in the source texts preserving the fragments. Almost every Greek fragment is translated or summarized into Latin.

The digital versions of FHG vol. 1 (7.4 MB), FHG vol. 2 (6.4 MB), FHG vol. 3 (7.8 MB), FHG vol. 4 (7.4 MB), FHG vol. 5-1 (2.9 MB) and vol. 5-2 (3.9 MB) are now available online. They collect fragments of authors from the 6th century BC through the 2nd century CE, including Apollodorus of Athens (with fragments of the Bibliotheca), historians of Sicily (Antiochus of Syracuse, Philistus of Syracuse, Timaeus of Tauromenius), the Atthidographers (Clidemus, Phanodemus, Androtio, Demo, Philochorus, and Ister), Aristotle and his disciples, historians from the time of Alexander the Great until 306 CE, fragments from the beginning of the reign of Constantine (306 CE) through the reign of the emperor Phocas (602-610 CE) and Greek and Syriac historical fragments preserved in Armenian texts. The Greek texts of the Marmor Parium (with Latin translation, chronological table, and commentary) and of the Marmor Rosettanum (with a French literal translation as well as a critical, historical and archaeological commentary) are online in a seperate appendix at the end of vol. 1.

The Müller-Jacoby Table of Concordance lists correspondences among Greek fragmentary historians published by Karl Müller in the Fragmenta Historicorum Graecorum (FHG) and by Felix Jacoby and other scholars in the Fragmente der griechischen Historiker (FGrHist), including the continuatio and the Brill's New Jacoby (BNJ).

FHG

The Fragmenta Historicorum Graecorum (FHG) is the first big collection of ancient Greek historical fragments ever realized. The five volumes have been edited by Karl Müller with the help of Theodor Müller and Victor Langlois. The work has been printed in Paris between 1841 and 1872 by the publisher Ambroise Firmin-Didot.

Digitization

The five volumes of the FHG are freely available online through Google Books and Internet Archive. The complete text of the work has been OCRed and converted to a machine-readable format as part of the Open Greek and Latin Project of the Alexander von Humboldt Chair of Digital Humanities at the University of Leipzig.

Development

The digital version of the FHG has been produced starting from the OCR output of the printed edition. Combining philological work and scripts, an SQL database has been created for delivering web services and tools. The raw data files are inserted into the SQL DB enriched with information useful to perform searches and citation extraction. Web pages are created using Ajax to retrieve data from the DB in order to increase the usability of the huge amount of FHG contents.

5 FHG volumes
636 FHG authors
1200 FHG works
7256 Fragments
8213 Source Texts
2315704 Words

Tools

The DFHG is the online version of the Fragmenta Historicorum Graecorum (FHG) edited by Karl Müller. The DFHG offers an easier and deeper access to the FHG thanks to a rich set of capabilities and tools that take advantage of web technologies and database functionalities. The DFHG appears as an Ajax web page automatically generated by a PHP script querying an SQL database of FHG contents. The DFHG is accessible by browsing the whole collection or selecting a single volume.

Slide In/Out Navigation Menu and Main Page

The DFHG slide in/out navigation menu, which is accessible through the icon on the top left hand side of the header bar, represents the whole tree of volumes, books, authors, works, and fragments collected in the printed edition of the FHG. The navigation menu is available for the entire collection and for each volume. The "Expand All" and "Collapse All" functions allow scholars to navigate the FHG with a comprehensive view of the structure of every volume. The + and - buttons give the possibility to expand and collapse each volume, book, author, and work down to the fragment level. Following the link to each navigation menu element, users are able to jump to the relevant section of the FHG without reloading the page. The slide in/out navigation menu includes:

  1. FHG volumina (FHG 1-5),
  2. praefationes (FHG 1, 2, 4 and 5),
  3. libri and other volume divisions (FHG 1-5),
  4. list of authors, works, books, and fragments (FHG 1-5),
  5. index nominum et rerum (FHG 1),
  6. index marmoris rosettani (Table de mots grecs, et des principaux faits expliqués) (FHG 1),
  7. addenda et corrigenda (FHG 1-5).

The DFHG main page (37 MB) is constituted by:

  1. introductions to FHG authors with notes accessible by hovering the mouse over the red note numbers;
  2. five-item rows for each fragment with:
    1. fragment number with link to the relevant page of the printed edition of the FHG, link to the words of FHG 1 fragments that are collected in the index nominum et rerum and to the words of the Rosetta Stone commentary that are in the index marmoris rosettani (bookmark icon ), and link to the OpenNLP POSTagger for Ancient Greek (tag icon ),
    2. reference to the source text of the fragment (sometimes with a short or long commentary),
    3. Greek or Latin text of the fragment,
    4. Latin (or French) translation/summary of Greek fragments,
    5. Latin (or French) commentary to the text of the fragment;
  3. two- or three-item rows for still surviving sources (e.g., Apollodorus' Bibliotheca, the Marmor Parium, and the Marmor Rosettanum in FHG 1, or Diodorus Siculus in FHG 2) with:
    1. Greek text,
    2. Latin (or French) translation,
    3. commentary (sometimes with notes).

The grey sidebar of the main page shows the original arrangement of pages in the FHG with links to the printed edition available through Google Books.

Search

DFHG contents (introductions, fragments, translations, commentaries, and source texts) are searchable in two different ways:

  1. by holding down the SHIFT-key when highlighting words with the mouse in the DFHG main page of the entire collection and of each volume;
  2. by searching words directly in the search tool.
The search is performed on fragments, translations, commentaries, and source texts. Results show the number of occurrences in each DFHG author and are organized by authors and works. Searched words are highlighted in the resulted texts of the DFHG. When available, results display also Morpheus' inflected forms and lemmata, and Suda's entries.

URNs

Each DFHG slide in/out navigation menu element has a unique identifier expressed as a URN. The syntax of each URN represents the editorial work of Karl Müller, who has arranged the fragments in a sequence and has attributed them to fragmentary authors, works, work sections, and book numbers.

For example:

A URN identifies itself as a URN in the LOFTS domain (urn). lofts stands for the Leipzig Open Fragmentary Texts Series and identifies the domain of textual fragments (i.e., texts preserved as quotations and text reuses in later sources). Work titles in the URN are expressed in the Latin translation provided by Müller in the printed edition of the FHG.

As URNs, these identifiers are not web-resolvable on their own. By combining them with a URL prefix (http://www.dfhg-project.org/DFHG/#), we have resolvable and stable identifiers.

The DFHG project provides also CITE URNs according to the CTS/CITE Architecture. CITE URNs are accessible through the DFHG API and through the Müller-Jacoby Table of Concordance.

Citations

Using URN identifiers, it is possible to export citations of DFHG fragments and source texts down to the word level. By selecting a portion of text holding down the ALT-key, users get a pop-up window with the URN that identifies the selected chunk of text.

For example:

  • urn:lofts:fhg.1.ephorus.ephori_fragmenta.historiae.liber_tertius:37@περιθοῖδαι[1]-ἰξίονος[1] identifies the sentence Περιθοῖδαι, δῆμος τῆς Οἰνηίδος φυλῆς, ἀπὸ Πειρίθου τοῦ Ἰξίονος in Ephorus' fragment 37.
  • Books and chapters are expressed in the Latin form provided by Müller in the printed edition of the FHG.

Integration

One of the main goals of the project is to integrate the DFHG with external resources such as textual collections, authority lists, dictionaries, and lexica. As for now

  1. the DFHG main page is connected to:
    1. the printed edition of the FHG available through Google Books,
    2. the 8,427 entries of the index nominum et rerum (FHG 1),
    3. the 249 entries of the index marmoris rosettani (FHG 1),
    4. the OpenNLP POSTagger for Ancient Greek;
  2. the DFHG search tool is connected to:
    1. the corresponding fragment in the main page,
    2. Morpheus, the morphological parsing and lemmatising tool of the Perseus Project,
    3. the Suda On Line.

Morpheus' entries still require a work of disambiguation and correction. The connection with Morpheus aims not only at getting inflected forms and lemmata of words of the DFHG corpus, but also at contributing to Morpheus by checking and correcting errors.

The index nominum et rerum and the index marmoris rosettani of FHG 1 have been created starting from the OCR output of their printed version. The selection and the arrangement of the entries depend on the editorial decisions of Karl Müller.

Additional Tools

Digger

The DFHG Digger filters the FHG according to authors, works, work sections, and book numbers. By typing and selecting through a live search, users can display the desired part of the collection. It is possible to combine filters using logical AND/OR expressions to get a more precise selection.

For example:

  1. work: ΑΤΘΙΣ
  2. author: CHARON AND work: ΠΕΡΣΙΚΑ

OCR Editing

The DFHG is based on the digitization of the five volumes of the FHG. Even if nowadays we are able to get good results when OCRing 19th century editions of ancient Greek and Latin sources, it is still possible to find errors in the OCRed texts. The DFHG offers the possibility to edit and correct these errors.

When searching the FHG with the search tool, an edit button appears on the right side of each row displaying the results. This button allows users to get a new window for suggesting corrections in the text of source texts, fragments, Latin translations, and commentaries. The correction will be validated or rejected by the project team through an administration page.

API

An API can be queried with DFHG author names and fragment numbers. The result is a JSON output containing every piece of information about the requested fragment.

For example:

Outputs

The DFHG can export data stored in the DFHG database in various formats:

  1. CSV format files;
  2. XML format files.

Müller-Jacoby Table of Concordance

The Müller-Jacoby Table of Concordance is a tool developed by the DFHG Project for finding correspondences among Greek fragmentary historians published by Karl Müller in the Fragmenta Historicorum Graecorum (FHG) and by Felix Jacoby and other scholars in the Fragmente der griechischen Historiker (FGrHist), including the continuatio and the Brill's New Jacoby (BNJ).

The Concordance includes also alphabetical lists of authors published in the FHG, the FGrHist, and the BNJ.
