Although Jersey was part of the Roman world, there is a lack of evidence to give a better understanding of the island during the Gallo-Roman and early Middle Ages. The tradition is that the island was called "Caesarea" by the Romans as laid down in the Antonine Itinerary, however this is disputed by some, who claim "Caesarea", "Sarnia" and "Riduna" are the Scilly Isles off the southwestern tip of England, nevertheless "Sarnia" in particular has a large cultural influence as the historic name of Guernsey (for example the national anthem of Guernsey is "Sarnia chérie"). "Andium" however is also mentioned on the list and this name is very often attributed to Jersey. Therefore, it is possible another island, such as the Minquiers were in fact "Caesarea" and Jersey "Andium".
