A auxiliary science is the one that works like support of other science so that it meets its goals and objectives. These are scientific disciplines that can complement to a science in certain specific cases.
Although the term may refer to different sciences, the notion of auxiliary sciences is closely linked to the history . That is why there are cases in which the mention of auxiliary sciences makes explicit reference to the Auxiliary sciences of history .
Archeology, the right and etymology are some of the auxiliary sciences that provide documentation or sources of analysis to the historian. These are, in most cases, autonomous sciences that have their own methodologies, which makes the idea of auxiliary science not accurate and, for this reason, has fallen into disuse.
All this without forgetting that there are other disciplines that can also be classified as auxiliary sciences of history. This would be the case, for example, of chronology, geography, iconography, heraldry, paleontology, geology, ethnography or papyrology.
However, all those mentioned can establish that they are grouped into two sets: the major auxiliary sciences, which are at the same level as the history in terms of degree of development, and the minor auxiliary sciences, which basically are responsible for checking sources of information.
These auxiliary disciplines help the historian to analyze documents or relics and, in this way, know their historical origin, extract data and generate new information. The collaboration of specialists (for example, from an archaeologist) is essential in many situations.
Several of the auxiliary sciences were developed from the study of issues that vary with the passage of time (such as chronology), while others arose from the comparison between different realities or factors (such as art history or the history of right).
It should be noted that the written record of history is known as historiography . Therefore, historiography constitutes the epistemology of history.
However, there are also other disciplines, in addition to history, which also have their own auxiliary sciences. This would be the case, for example, of Criminal Law. In their case, they are considered disciplines that support legal medicine, criminalistics, criminal statistics or forensic psychiatry.
The aforementioned legal medicine is responsible for ruling the causes of the death of a person while the criminal is the one that, through certain procedures, carries out what is the collection of evidence and elements of different types that allow to clearly identify the author of said death or criminal act.
Criminal statistics, on the other hand, can establish that it is that auxiliary science of Criminal Law that has as its object of work the quantitative determination of crime rates in a given area. And finally, forensic psychiatry can establish that it is the discipline that undertakes the study of the behavior of the offender itself with the clear objective of determining if there are certain ideas or elements in his head that prevent him from realizing the seriousness of the facts.
