Passage: Levantine Art was first discovered in Teruel in 1903. The Spanish prehistorian Juan Cabre was the first to study this art, defining it as a regional Palaeolithic art. Assessment as Palaeolithic was challenged for various reasons including the fact that no glacial fauna was depicted. Antonio Beltrán Martínez and others place the beginning of this art in the Epipaleolithic or Mesolithic, placing its heyday in the Neolithic period. Accepting a post-Paleolithic age for the art, Ripio devised a new chronological scheme in the 1960s, dividing the art into four stages:naturalistic, stylized static, stylized dynamic, and final phase of transition to the schematic.
