Anchieta began to translate Catholic prayers and biblical stories into the language. Another foreigner, Jean de Lery, wrote the first (and possibly only) Tupi "phrasebook", in which he transcribed entire dialogues. Lery's work is the best available record of how Tupi was actually spoken. In the first two or three centuries of Brazilian history, nearly all colonists coming to Brazil would learn the tupinambá variant of Tupi, as a means of communication with both the Indigenous people and with other early colonists who had adopted the language. The Jesuits, however, not only learned to speak tupinambá, but also encouraged the Indians to keep it. As a part of their missionary work, they translated some literature into it and also produced some original work written directly in Tupi. José de Anchieta reportedly wrote more than 4,000 lines of poetry in tupinambá (which he called lingua Brasilica) and the first Tupi grammar. Luís Figueira was another important figure of this time, who wrote the second Tupi grammar, published in 1621. In the second half of the 18th century, the works of Anchieta and Figueira were republished and Father Bettendorf wrote a new and more complete catechism. By that time, the language had made its way into the clergy and was the de facto national language of Brazil – though it was probably seldom written, as the Roman Catholic Church held a near monopoly of literacy. When the Portuguese Prime Minister Marquis of Pombal expelled the Jesuits from Brazil in 1759, the language started to wane fast, as few Brazilians were literate in it. Besides, a new rush of Portuguese immigration had been taking place since the early 18th century, due to the discovery of gold, diamonds, and gems in the interior of Brazil; these new colonists spoke only their mother tongue. Old Tupi survived as a spoken language (used by Europeans and Indian populations alike) only in isolated inland areas, far from the major urban centres. Its use by a few non-Indian speakers in those isolated areas would last for over a century still. Tupi research When the Portuguese first arrived on the shores of modern-day Brazil, most of the tribes they encountered spoke very closely related dialects. The Portuguese (and particularly the Jesuit priests who accompanied them) set out to proselytise the natives. To do so most effectively, doing so in the natives' own languages was convenient, so the first Europeans
