Lisbon's name may have been derived from Proto-Celtic or Celtic ''Olisippo'', ''Lissoppo'', or a similar name which other visiting peoples like the ancient Phoenicians, Greeks and Romans adapted accordingly, such as the pre-Roman appellation for the Tagus River, ''Lisso'' or ''Lucio''.  Classical authors writing in Latin and Greek, including Strabo, Solinus, and Martianus Capella, referred to popular legends that the city of Lisbon was founded by the mythical hero Ulysses (Odysseus). Lisbon's name was written ''Ulyssippo'' in Latin by the geographer Pomponius Mela, a native of Hispania. It was later referred to as "Olisippo" by Pliny the Elder and by the Greeks as ''Olissipo'' (Ὀλισσιπών) or ''Olissipona'' (Ὀλισσιπόνα).
