of Ricci's comrade Diego de Pantoja, which was published in Europe along with other Jesuits' letters in 1605. The Jesuits in India, however, were not convinced, because, according to their informants (merchants who visited the Mughal capitals Agra and Lahore), Cathay – a country that could be reached via Kashgar – had a large Christian population, while the Jesuits in China had not found any Christians there. In retrospect, the Central Asian Muslim informants' idea of the Ming China being a heavily Christian country may be explained by numerous similarities between Christian and Buddhist ecclesiastical rituals – from having sumptuous statuary and ecclesiastical robes to Gregorian chant – which would make the two religions appear externally similar to a Muslim merchant. This may also have been the genesis of the Prester John myth. To resolve the China–Cathay controversy, the India Jesuits sent a Portuguese lay brother, Bento de Góis, on an overland expedition north and east, with the goal of reaching Cathay and finding out once and for all whether it is China or some other country. Góis spent almost three years (1603–1605) crossing Afghanistan, Badakhshan, Kashgaria, and Kingdom of Cialis with Muslim trade caravans. In 1605, in Cialis, he, too, became convinced that his destination is China, as he met the members of a caravan returning from Beijing to Kashgar, who told them about staying in the same Beijing inn with Portuguese Jesuits. (In fact, those were the same very "Saracens" who had, a few months earlier, confirmed it to Ricci that they were in "Cathay"). De Góis died in Suzhou, Gansu – the first Ming China city he reached – while waiting for an entry permit to proceed toward Beijing; but, in the words of Henry Yule, it was his expedition that made "Cathay... finally disappear from view, leaving China only in the mouths and minds of men". Ricci's and de Gois' conclusion was not, however, completely convincing for everybody in Europe yet. Samuel Purchas, who in 1625 published an English translation of Pantoja's letter and Ricci's account, thought that perhaps Cathay still can be found somewhere north of China. In this period, many cartographers were placing Cathay on the Pacific coast, north of Beijing (Pekin) which was already well known to Europeans. The borders drawn on some of these maps would first make Cathay the northeastern section of China (e.g. 1595 map by Gerardus Mercator), or, later,
