The distinguishing feature of a descent from antiquity compared to a traditional pedigree is the intent to establish a historically verifiable generation-by-generation descent, unlike the legendary descents found in medieval genealogical sources and modern
pseudogenealogy in books like
The Holy Blood and the Holy Grail and
The Da Vinci Code. DFA research has focused on the ancestries of royal and noble families, especially the possible genealogical links between the new dynasties of western Europe from which well-documented descents are known, such as the
Carolingians,
Robertians,
Cerdicings, and the
Astur-Leonese dynasty, back through the ruling families of the post-Roman Germanic dynasties and Franco-Romans, all the way to the gentility of the Roman Empire, or in the Eastern Mediterranean linking the royal Armenian wives of some
Byzantine emperors through the ruling families of the
Caucasus to the rulers of the
Hellenistic,
Parthian, and Roman-client kingdoms of the Middle East. The phrase
descent from antiquity was used by
Tobias Smollett in the 18th-century newspaper
The Critical Review. Reviewing
William Betham's
Genealogical Tables of the Sovereigns of the World, from the earliest to the present period, he wrote "From a barren list of names we learn who were the fathers or mothers, or more distant progenitors, of the select few, who are able to trace what is called their descent from antiquity." The possibility of establishing a DFA as a result of serious genealogical research was raised in a pair of influential essays, by
Iain Moncreiffe and
Anthony Wagner. Wagner explored the reasons why it was difficult to do and suggested several possible methods. The following years have seen a number of studies of possible methods by which an appropriately documented ancestry might be found. These methods typically involve either linkages among the ruling dynasties of the post-Roman Empire Germanic states, or those between the ancient dynasties of the Caucasus and the rulers of the Byzantine Empire. Though based largely on historical documentation, these proposed methods have invariably resorted to speculation based on known political relationships and onomastics; for example, the tendency of families to name children in honor of relatives is used as evidence for hypothesized relationships between people bearing the same name. Proposed DFAs vary greatly both in the quality of their research and the degree to which speculation plays a role in their proposed connections. No European DFA is accepted as established. The outlines of several
possible ancestries that could become DFAs have been proposed, but they each lack crucial evidence. Nonetheless, the pursuit of DFAs has stimulated detailed inquiry into the
prosopography of ancient and early medieval societies. ==See also==
