I want to know the answer to the following question:
What is one of the earliest surviving records that mention the name British Isles?
All the background I'm provided with is that "The original records have been lost; however, later writings, e.g. Avienus's Ora maritima, that quoted from the Massaliote Periplus (6th century BC) and from Pytheas's On the Ocean (circa 325–320 BC) have survived.". Is that enough to answer the question?
Answer: yes
