He is credited with the development of landscape painting as a discipline in France as he was one of the first to paint and display landscapes there ("Landscape with Orpheus and Eurydice" (around 1555) on display in the National Gallery, London). His pictures exhibit a combination of skill in drawing, grace and natural coloring. Some of his easel pieces in oil are in different collections; one of them, "The Martyrdom of St. Peter and St. Paul", is in the Dresden gallery.
Abatis, Abattis or Abbattis (a French word meaning a heap of material thrown), a term in field fortification for an obstacle formed of the branches of trees laid in a row, with the tops directed towards the enemy and interlaced or tied with wire.
The abatis is used alone or in combination with wire entanglements and other obstacles.
Also, a form of giant abatis, using whole trees instead of branches, can be used as an anti-tank obstacle.
