Latin prepositions <i>ab </i>and <i>ex </i>with place-names in Pliny's <i>Natural History</i>
The paper based on Pliny's Natural History shows similarities and difference in the use of Latin prepositions ab and ex with place-names. The difference is that ab may be used with any place-names to denote separation, as well as to indicate distances, whereas ex is used when talking about rivers that flow from springs, other rivers, or mountains. Both prepositions can be used with words meaning "import" ( inveho, adporto ). In this case ab is used with town-names, ex is used with any other place- names.
