A couple of weeks ago Dr. Ben Dykes- one of my favourite translators, one of the very few to have a proper curriculum studiorum, when the greater part has a self education, ie no title and competence – posted in Deborah Houlding site a preview of his last work Persian nativities– which includes al-Khayyat’s Judgement on nativities, and Liber Aristotilis, a work written by Mashallah and then translated in Latin by Hugo of Santalla around 1100, which is more interesting for me.
