In the early 1980s, Elblag archaeologist M. Jagodziński discovered the remains of a large early-medieval production and trading settlement on the shores of Lake Druzno, to the southeast of Elblag. After more than 30 years, they are believed to be the remains of the commercial emporium of Truso mentioned in Wulfston’s sailing report from the end of the ninth century. Contemporary archaeological research is the cumulation of the centuries-long search for Truso and the study of Wulfstan’s report, conducted in several European countries by several dozen scholars of different nationalities. In this article the author attempts to present the course of this scientific process in the fullest possible extent, initiated by Halkuyt’s publication in 1599 and ending in 1873, from which time these studies became almost exclusively the domain of archaeologists.
