A map showing the cities and towns affected by the eruption of Mount Vesuvius in 79 AD.  The general shape of the ash and cinder fall (see <a href="https://en.wikipedia.org/wiki/en:pyroclast" class="extiw" title="w:en:pyroclast">w:en:pyroclast</a>) is shown by the dark area to the southeast of Mt Vesuvius.    (P.S. It seems strange to show the modern day English names for the two bodies of water - I am open to suggestions).
This map shows lines and uses the Mercator projection (although that is not important on a map of this scale).  North is, as usual, at the top of the map.
