Task: Question Generation
Input (English): Passage: A brief article mentioning the discovery appeared in the Maidstone Journal on 4 July 1822; the information in it was then largely repeated in a volume of the Gentleman's Magazine that year. The latter also features some brief discussion as to who the deceased individuals in the chamber had been, speculating that it was "some chief slain in the battle fought here between Vortimer, King of Britain, and the Saxons". A second description of the site appeared in Gentleman's Magazine in 1834, written by S. C. Lampreys.About a year after the discovery, Smythe wrote an account in which he included both a sketch and plan of the chamber. Smythe's original report was not published at the time, but deposited in the archive of Maidstone Museum. In this unpublished document, he referred to the monument as a "British Tomb" or a "Druidical Monument". The document was only published in 1948, in an article written for the Archaeologia Cantiana journal by the archaeologist John H. Evans. Evans noted that "meagre and incomplete as it is", "we must be grateful" for this document "when we remember the unrecorded destruction wrought throughout the centuries upon this interesting and isolated megalithic necropolis".Alongside Smythe's report, another brief account was also produced and placed in the museum, likely written by Charles and again published in Evans' 1948 article. Ashbee later related that both of the reports written in the 1820s were "brief but valuable" and "in many ways in advance of their age". He noted that the destruction of prehistoric monuments during this "age of agricultural development" would have been quite commonplace and thus these antiquarians' records — written "almost half a century before the emergence of the outlines of present-day prehistory" as a field of scholarly study — were particularly important.In the 1920s, the archaeologist O. G. S. Crawford accessed the Maidstone Museum archives to determine the probable location of Smythe's Megalith. He then included it in his 1924 Ordnance Survey guide to archaeological sites in southeastern England. In 1955, several substantial stones were also found in the area. In 2000, Ashbee stated that some of the kerbstones had "recently come to light, buried in the ditches" of the monument.
