Auxiliary Sciences of History


The auxiliary sciences of history (ASH) are those sciences which bolster the discipline of history. The sciences included in the ASH vary depending on which source you’re looking at. A few commonly named ones are chronology, paleography, and numismatics. I discuss the fuller smorgasbord of included sciences throughout this article.

The ASH are sometimes called the ancillary sciences of history. Given that both words begin with the letter A, the abbreviation ASH can stand for either of the terms. In this present context, ancillary and auxiliary are synonymous and they mean “the supporting”, as in “the supporting” sciences of history.

To my knowledge, the literature about the concept of the ASH and their history is scarce. From what I’ve seen, the ASH are typically referred to in passing and make up a notably small portion of the text in which they’re mentioned. In this article, I provide my study into the history of the concept of the ASH.

Although many of the ASH have roots in the 16th century, the earliest mention of the auxiliary sciences that I’m currently aware of was made in 1801. The term appears to have gained some popularity from about 1890 to 1930. See the Quotes & Commentary section for more information.

“The University of Göttingen was the first to cultivate the study of these auxiliary sciences in Germany during the 18th century.”[15]



Usage Frequency

There are some ASH that appear more frequently than others in the literature about the ASH. Based on the references in this article, I tallied up how many times each ASH was named. Out of the 46 included ASH, 27 (58.69) of them were named only once.

The ASH in this section are organized by the number of time they were mentioned by my references. Diplomatics was mentioned 12 times, same as paleography. Chronology was mentioned 11 times. That’s what the first number represents. The number in the parentheses indicated how many ASH are listed in each set.

12 (2): Diplomatics, Paleography

11 (1): Chronology

8 (1): Numismatics

6 (2): Archeology, Sphragistics/Sigillography

5 (3): Epigraphy, Genealogy, Heraldry

4 (2): Geography, Philology

3 (4): Anthropology, Archivistics, Codicology, Linguistics

2 (4): Bibliography, Historical Geography, Sociology, Statistics

1 (27): Archaeography, Canon Law, Cartography, Chemistry, Chorography, Cliometrics, Comparative Jurisprudence, Diplomacy, Hagriography, Historical Criticism, Liturgy, Medieval Archeology, Method, Onomastics, Politics, Phaleristics, Philately, Philosophy, Physics, Political Economy, Prosopography, Psychology, Scholasticism, Theology, Toponymy, Vexillology

Quotes & Commentary

“Jos. Jus. Scaliger (died 1609), was the principal author of the seventeenth century that largely contributed to the improvement of the auxiliary sciences of history, in general.”
– Whittingham, et al. (1801)[2, p.387]

“In the same line of usefulness I place all that group of studies which have as yet no fixed name in America, but which are known in Europe as the auxiliary sciences of history. These have reference to history as a whole, and are of use to any one who means to be a thorough student in it. They include chronology, geography, anthropology, numismatics, diplomatics, sphragistics, heraldry, and paleography.”
– American Historical Association (1894)[3, p.86]

“M. Langlois rightly holds that of all the auxiliary sciences relating to historical study, that of bibliography is the most useful and the most neglected. A course in bibliography has generally been confined to future librarians, but M. Langlois insists upon it that students of every art and science should be properly instructed in bibliography, that they may use all existing bibliographical tools to advantage and avoid giving time and wearing research to the production of books relating to subjects already covered far more authoritatively than they can hope to emulate.”
– The Publishers Weekly: Volume 49 (1896)[4, p.987]

“All sciences stand in some relation to each other, and one aids and explains the other. In this wide sense we might say that all the philosophical, mathematical, physical and philological sciences stand in some relation to history; but even in a stricter sense many sciences, like chronology, geography, genealogy, diplomacy, sphragistics, heraldry, numismatics, and statistics are the essential auxiliary sciences of history, and they receive much light from her. History is … the mother of half of the sciences.”
– Association of Catholic Colleges of the United States (1899)[5, p.73]

Two groups were identified in 1904: the auxiliary historical sciences and the purely auxiliary sciences.[6]
Auxiliary historical sciences:
1. “Archeology (which is the general science of the monumental remains and the customary objects of past generations)”[6, p.462]
a. artistic archeology
b. sigillography or sphragistics
c. numismatics
d. iconography
e. heraldry
f. archeology of customs
2. “Epigraphy (which comprises those sciences required in the deciphering and criticism of ancient engraved inscriptions)…”[6, p.462]
3. “Paleography (which is the art of reading ancient documents written on parchment, papyrus or paper)”[6, p.462]
4. “Diplomatics (which teaches the use of those documents not yet available for historical purposes)”[6, p.462]
5. “Historical criticism (which teaches the use, etc., of the chronicles)”[6, p.462]
6. “Chronology (which fixes events)”[6, p.462]
7. Genealogy
8. “Archivistics (which is the art of preserving and arranging ancient written documents)”[6, p.462]

“The progress of history as a science must depend largely in the future as in the past upon the development of cognate sciences, — politics, comparative jurisprudence, political economy, anthropology, sociology, perhaps above all of psychology. It is these sciences which have modified most fundamentally the content of history, freed it from the trammels of literature, and supplied scientific canons for the study of manking. They are the auxiliary sciences of history in a far deeper sense than are paleography, diplomatics, or even philology. The sciences relating to mankind will hereafter dominate the work of the historian.”
– James Harvey Robinson (1905)[9, p.51]

“The modern science of History has been so rigorously shaped by academic method and so deeply overlaid with materials from newly-discovered sources that some discrimination is needed in discussing the most trivial aspects of its study. Again, the rival claims of Universal History (with its huge excrescence known as Sociology) of General History (with its invitation to include the history of every science or art within our ken) of Political, Constitutional, Legal, Ecclesiastical, Naval and Military, Economic and Social History, and even the well-defined and exacting auxiliary sciences of History in the shape of Bibliography, Method, Linguistic, Paleography and Diplomatic, Archeology and the other hard terms with which the studies of coins and medals, seals, dates and pedigrees are labelled by the learned, have each to be duly considered even by those who aspire to no more than a modest knowledge of the history of their own country.”
– Y Cymmrodor (1907)[10, p.1]

“Finally, courses in the auxiliary sciences of history were organized little by little, and entered on the program of the faculties of theology and of philosophy and letters as optional studies, namely, in 1864, Christian archeology, and in 1881, paleography, chronology and diplomacy.”
– The Catholic University Bulletin (1907)[8, p.519]

“Chief among [the “auxiliary sciences” of history] are language, as a means to understanding of historical records; paleography, or the science of ancient writings; diplomatics, treating of official documents; epigraphy, or the science of inscriptions; numismatics, archeology, chronology, and historical geography.”
– A Cyclopedia of Education (1912)[11, p.253]

“For the ecclesiastical historian the chief auxiliary sciences are: Philosophy, and especially Scholasticism; Theology, both dogmatic and moral; Canon Law, which properly judged in its relation to Church history, is the Gospel of Christ in actual practice amongst Christians; Liturgy, and Hagiography. Theology is of supreme importance.”
– The Catholic Historical Review (1915)[12, p.359]

“Charles Victor Langlois … made contributions of the greatest importance to mediaeval scholarship and to the auxiliary sciences of history.”
– James F. Willard (1924)[13, p.66]

“…the auxiliary sciences of history … philology, diplomatic, paleography, chronology, and geography. Other sciences subordinate to these are brought into the circle as subordinate helps.”
– Peter Guilday (1925)[1, p.199]
