In the 19th century, a Hungarian baron Jόsef Kemény concocted an inscription, in a ‘Proto-Hungarian’ dialect, which was said to have been written on a statuette representing a winged sphinx, but no one saw it, because there was no such thing ever, being rendered only as a black-and-white drawing. The statuette would have been ‘discovered’ in Potaissa (present day Turda, Romania), dating from the 3rd century AD, during the last years of Roman occupation of Dacia. As early as the 19th century, a number of researchers already proved it to be a fake. However, the idea has recently been revived, so that at the end of December 2023 an article appeared in an English-language journal signed, this time, by a Hungarian professor settled in the USA. His name is Peter Z. Revesz, a professor at Nebraska University. Our professor ‘deciphers’ the inscription in question. On his part, the author of the present article gathers all the data available to him and proves that the effort of the American researcher was in vain.
