The majority of treatises on agriculture in al-Andalus can be found in miscellaneous codexes which are mainly attributed to only one author, which has brought about a number of false attributions of authorship we will analyse in this research. We then make a brief study of the different miscellaneous manuscripts, studying the different attributions to which they have been object more in detail so as to attempt to mark the boundaries of each one. This study is summarized in a table. (...) Finally, we discuss the more significant data from the previous information, adding some references about the influence the works of the agronomical school of al-Andalus had. (shrink)
