I've been trying to gather a more complete picture of the available information regarding the survival of Romance dialects in Sicily during the Arab and Eastern Roman periods. I've found this forum post. That seems to offer some opinions on this issue, but I'm having a hard time identifying which works are viewed as most reliable on this topic, and what primary sources we have available. Does anyone have any insight? Primarily my question is: What evidence do we have to support or refute the question: "Were Romance dialects present in Sicily before the arrival of the Normans?" Thanks guys!
