own report on the discovery, entitled ''Monograph on Buddha Sakyamuni's birthplace'', 1897 Following the discovery of the pillar, Führer relied on the accounts of ancient Chinese pilgrims to search for
Kapilavastu, which he thought had to be in
Tilaurakot. Unable to find anything significant, he started excavating some structures at Sagarwa, which he said were stupas of the
Shakyas, and was in the process of faking pre-Mauryan inscriptions on bricks, when he was caught in the act by Vincent Arthur Smith. Soon after, Alois Anton Führer was exposed as "a forger and dealer in fake antiquities", and had to resign from his position in 1898. Vincent Arthur Smith further revealed in 1901 the blunt truth about Führer's Nepalese discoveries, saying of Führer's description of the archaeological remains at Nigali Sagar that "every word of it is false", and characterizing several of Führer's epigraphic discoveries in the area, including the inscriptions at the alleged Shakya stupas at Sagarwa, as "impudent forgeries". It was finally understood in 1901 that Führer had copied almost word-for-word this description from a report by
Alexander Cunningham about the stupas in
Sanchi. However Smith never challenged the authenticity of the Lumbini pillar inscription and the Nigali Sagar inscription, and accepted the identifications as authentic. which was withdrawn from circulation.
Forged Brahmi inscriptions by Führer In 1912, the German Indologist
Heinrich Lüders identified in the
Lucknow Provincial Museum (of which Führer had been curator) several forged inscriptions in Brahmi on artifacts belonging to Führer's 1889–1891 excavations at
Mathura and the
Ramnagar site of
Ahichchhatra, forgeries which he attributed to Führer himself. Some of the forged inscriptions were direct copies of inscriptions on other objects, previously published in
Epigraphia Indica. In particular Lüders was able to show that supposed Jain inscriptions were fakes compiled from earlier real inscriptions found in
Mathura. Of the Mathura inscriptions discovered by Führer, Lüders summarized in 1912 that "As all statements about epigraphical finds that admit of verification have proved to be false, it is very likely that no inscriptions at all have turned up". and that "features of truly Aśokan script, some of them extinct at the middle of the second century BC" could not realistically have been forged by Führer who was "extremely clumsy", "ill-educated in Prakrit phonology and morphology", and "ignorant to the same degree of Brāhmī palaeography," therefore "disqualifying Führer as the author of a perfect fake." ==Issues of authenticity==
