LGO Widget

The contents of the Lexicon of Gregory of Nyssa (LGO), a dictionary of Gregory of Nyssa's writings and terminology, has been added to Gregorii Nysseni Opera Omnia Online (GNOO) on Scholarly Editions. The contents is made accessible as a widget in the Reader. Users who have access to GNOO on SE will be able to use the widget.

LGO Widget How-to

The LGO Widget is a resource that is added to Gregorii Nysseni Opera Online on Brill Scholarly Editions.


LGO stands for Lexicon Gregorianum Online. It is a most comprehensive Greek-German dictionary of the language used by Gregory of Nyssa. It is an indispensable complement to Gregorii Nysseni Opera Online (GNOO), the authoritative edition of the complete works of the fourth-century Christian theologian Gregory of Nyssa. Far from being a simple word list, this seminal reference work documents Gregory's complete vocabulary, taking account of the syntax, meaning and connotations of every occurrence of a key word in his writings.

the widget - basics

The widget is located in the Reader of Brill Scholarly Editions. It sits in the right panel, below the citation widget.

For any GNOO text in the Reader, the LGO widget will display the lemmata it has for it. These are the headwords for any inflected forms as they may occur in the GNOO text.

Click on a lemma to display the LGO entry for that headword. LGO entries usually give the meaning of a word followed by illustrations of the word in context (i.e the works of Gregory of Nyssa). However, keep in mind that LGO entries can vary greatly in structure, size, and complexity. If a lemma consists of multiple sections, these are collapsible.

The section that contains an illustration of the meaning of the headword that corresponds to the GNOO passage that is open in the Reader will be opened by default.

Many of the illustrations contain hyperlinks. Click on them to go to the corresponding GNOO passage; it will open in the Reader.

the widget - advanced

It is possible to filter the headwords in the widget in those cases where many lemmata for a given (probably larger) number of passages are shown in the Reader.

Once an entry is selected, a menu will appear in the form of a small cogwheel. This gives the option to expand or collapse all sections of an entry. It can also toggle on and off the display of illustrations, with or without text, and with or without (clickable) GNOO references.
