Royllo (also Roillo), is a legendary phantom island that was once thought to be located in the Atlantic Ocean. It is probably identical with the island originally called Ymana in a 1424 nautical chart of Zuane Pizzigano. The island is usually depicted in many 15th-century maps as a small island located slightly to the west (20 leagues or so) of the much larger island of Antillia.[1] It is often found in the group insulae de novo repertae, or "newly discovered islands" along with other legendary islands.
