Antiquities and potteries of Roman origin were found in association with the finds of Indian origin.With the aid of these dated imports it was possible to date the associated Indian objects to the first two centuries A. Similarly NBP and PGW has helped in fixing the chronology of numerous sites. Sometimes dates are also obtained with the assistance of astronomy.In archaeology, dating techniques fall into two broad categories: chronometric (sometimes called “absolute”) and relative.Chronometric dating techniques produce a specific chronological date or date range for some event in the past. Relative dating techniques, on the other hand, provide only the relative order in which events took place.This closely agrees with the fact that the seals from Indus Valley style from Ur, Kish and Tell Asmar and other sites fall within the range of 2500-1500 B. When a group or type of objects are found together under circumstances suggesting contemporanity they are said to be associated.It is nearly always association with other phenomena that gives a first clue as to the use, the age and chronological attribution of a potential datum, but age at least may sometimes be inferred from position in a geological deposit or a layer of peat.Without the ability to date archaeological sites and specific contexts within them, archaeologists would be unable to study cultural change and continuity over time.No wonder, then, that so much effort has been devoted to developing increasingly sophisticated and precise methods for determining when events happened in the past.
