Incredible RARE Antique 1500s-1700s European Quilt/Textile-Beautiful For Sale

Offered is this incredible quilt/textile from the 1500s. It is marked 1521 dii, which could be the date. Being that I am not 100% certain I would say this is no later than the 1700s. Has 2 stainings on the back lining and you can see some of the beautiful threading that is still retained throughout. It would have been an absolutely gorgeous work of art back in the day and still is in its current beauty. I would say this is a true rarity to have something that has survived this long. Portuguese-European most likely
