Recognizable strands in the contemporary ideas on universal languages took form only in Early Modern Europe. In the early 17th century some believed that a universal language would facilitate greater unity among mankind largely due to the subsequent spread of religion, specifically Christianity, as espoused in the works of Comenius. But there were ideas of a universal language apart from religion as well. A "lingua franca" or trade language was nothing very new; but an international auxiliary language was a natural wish in light of the gradual decline of Latin. Literature in vernacular languages became more prominent with the Renaissance. Over the course of the 18th century, learned works largely ceased to be written in Latin. According to Colton Booth ("Origin and Authority in Seventeenth-Century England" (1994) p. 174) "The Renaissance had no single view of Adamic language and its relation to human understanding." The question was more exactly posed in the work of Francis Bacon.
