Naples from the west / J. Drayton.

Starting in 1631, Vesuvius entered a period of steady volcanic activity, including lava flows and eruptions of ash and mud. Violent eruptions in the late 1700s, 1800s and early 1900s created more fissures, lava flows, and ash-and-gas explosions. These damaged or destroyed many towns around the volcano, and sometimes killed people; the eruption of 1906 had more than 100 casualties. The most recent eruption was in 1944 during World War II. It caused major problems for the newly-arrived Allied forces in Italy when ash and rocks from the eruption destroyed planes and forced evacuations at a nearby airbase.

Printmaking in woodcut and engraving came to Northern Italy within a few decades of their invention north of the Alps. Engraving probably came first to Florence in the 1440s, the goldsmith Maso Finiguerra (1426–64) used the technique. Italian engraving caught the very early Renaissance, 1460–1490. Print copying was a widely accepted practice, as well as copying of paintings viewed as images in their own right.
