Las ediciones de la Silua Selectorum Tripartita y del De Ratione Dicendi de Bartolomé Alcázar

The  Silua Selectorum Tripartita  and the  De ratione dicendi  with Aphthonius’  Progymnasmata  were published twice during the life of Bartolome Alcazar. First, in 1681 there appeared the  Silua Selectorum Tripartita , the second part of which, headed  Didactica , also contained the  Progymnasmata  of Aphthonius. Then, in the same year, this second part was published independently under the name  De ratione dicendi opusculum triplex . In 1688 this second part, entitled  De ratione dicendi , was reprinted with corrections and additions. In 1706 the entire first work, the  Sylua Selectorum Tripartita , was published again, but in a different structure than before. This paper analyses and compares these editions in order to establish their differences and to determine their modifications and similarities.
