This cloth was highly prized and imported from the Middle East. Over time, the word shifted to describe the specific vibrant red color associated with this fabric. The etymology traces back through Old French 'escarlate', Medieval Latin 'scarlata', and ultimately to Persian 'saqirlat' or Arabic 'siqillat', referring to a rich fabric.
