Task: Question Answering
Input (English): Passage: Archaeology confirms the widespread use of binding spells (defixiones), magical papyri and so-called "voodoo dolls" from a very early era. Around 250 defixiones have been recovered just from Roman Britain, in both urban and rural settings. Some seek straightforward, usually gruesome revenge, often for a lover's offense or rejection. Others appeal for divine redress of wrongs, in terms familiar to any Roman magistrate, and promise a portion of the value (usually small) of lost or stolen property in return for its restoration. None of these defixiones seem produced by, or on behalf of the elite, who had more immediate recourse to human law and justice. Similar traditions existed throughout the empire, persisting until around the 7th century AD, well into the Christian era. Question: Until what era did spells persist in the empire?
Output (English): 7th century AD
