Stemmatology is the global an umbrella term denoting for all scholarly and scientific studies involving a text's genealogy and focused on textual genealogy and the creation of a stemma codicum. It is usually concerned with reconstructing such a specific stemma starting from the basis of the surviving witnesses, but may also study deal with stemmata in a more abstract sense (hence this lexicon's name). The term is usually used synonymously as a synonym to stemmatics. As with many other fields, the endings -ology (from λόγος 'word, meaningful or scientific utterance') and -ic(s) (the adjective forming suffix -ικὴ with an intended feminine , feminine because the feminine noun τέχνη 'art, field of study' is intended) tend to be used for the same purpose, namely to label a 'scientific field about X'.If If a difference between the two terms is perceived, stemmatology tends to be the wider term, whereas stemmatics may be confined to the Lachmannian method.
The Latin term 'stemmatologia' was already in use in the 17th century in the work Stemmatologia Sangallensis oder Geschlecht-Register aller in der Stadt St.Gallen verbürgerten und sich noch im Wesen findenden Geschlechtern, [...] bis auf das Jahr 1732 von Johann Jacob Scherrer [...]. St. Gallen 1752-1769, 27 volumes. But here the stemmata it studies were people's genealogical trees and not yet those early 18th century, e.g. it appears in the title Stemmatologia Tigurina: Das ist Zürichisches Geschlechter Buch […] by Erhard Dürsteler (sine anno, but apparently printed between 1706 and 1724). But the stemmata included in this book were genealogical trees of human beings, not of manuscripts. The word stemmatographia was used synonymously (cf. J. Joseph Ramminger, stemmatographia, in ders.,: Neulateinische Wortliste. Ein Wörterbuch des Lateinischen von Petrarca bis 1700, URL: www.neulatein.de/words/1/001317.htm (used accessed on 12.12.2014)).
