Thus, to be considered as archaeological, the remains, objects or artifacts to be dated must be related to human activity.It is commonly assumed that if the remains or elements to be dated are older than the human species, the disciplines which study them are sciences such geology or paleontology, among some others.Thus, 1587 is the post quem dating of Shakespeare's play Henry V.That means that the play was without fail written after (in Latin, post) 1587.To the collector the mark has greater importance, for not only can he trace the manufacturer of any marked object, but he can also ascertain the approximate date of manufacture and in several cases the exact year of production, particularly in the case of 19th and 20th century wares from the leading firms which employed private dating systems.With the increasing use of ceramic marks in the 19th century, a large proportion of English pottery and porcelain can be accurately identified and often dated.
For a non-exhaustive list of relative dating methods and relative dating applications used in geology, paleontology or archaeology, see the following: Same as geologists or paleontologists, archaeologists are also brought to determine the age of ancient materials, but in their case the areas of their studies are restricted to the history of both ancient and recent humans.
But this method is also useful in many other disciplines.
Historians, for example, know that Shakespeare's play Henry V was not written before 1587 because Shakespeare's primary source for writing his play was the second edition of Raphael Holinshed's Chronicles, not published until 1587.
These are made so well that to recognize these fakes by just looking at the backstamp is almost impossible.
In the case of the larger firms the mark also has publicity value and shows the buyer that the object was made by a long-established firm with a reputation to uphold; such clear name- marks as Minton, Wedgwood, Royal Crown Derby and Royal Worcester are typical examples.
Thus, from the oldest to the youngest, all archaeological sites are likely to be dated by an appropriate method.
