Noticias bizantinas en Espa？a: El caso de San Isidoro de Sevilla

in his chronicon, st isidore of seville reports the invasion of the balkans by slavs in times of the emperor heraclius. this fact has led us to pose ourselves the question about how it was possible that this spanish author could be informed of events taking place not only far from spain, but which are scarcely mentioned in the byzantine sources. was it possible that the bishop received trustworthy information of events then taking place in the east? the author of the article believes that this was indeed the case and a short analysis of the visigothic-byzantine relations can answer this question, as well as who could be transmitters of such information and how st isidore was able to come by it.
