  Whereas in Western Europe, under the growing influence of humanism, the scholastic tradition of terminist logic came to an end in the third decade of the 16th century, it had a vigorous, though not unaltered, continuation on the Iberian Peninsula until the 18th century. From there it was re-imported to the universities and academic schools in Western Europe, after the late 16th and early 17th century, mainly but not exclusively in Catholic areas. Even if the scholastic doctrine of signs was presented in a so to speak “light version” by authors like Domingo de Soto[63]  and Franciscus Toletus, the rudiments of medieval semiotics transmitted through their writings, provided the groundwork on which a great number of 17th-century logicians were developing a highly elaborated sign theory (Meier-Oeser 1997, 171–335). The most important of these are the so-called Conimbricenses, John of St. Thomas (alias John Poinsot), Peter of Candamo and Silvester Aranha, but a large number of texts is still awaiting to be explored.
