paragraph_text: Computational and virtual archaeology
  
  Computer graphics are now used to build virtual 3D models of sites, such as the throne room of an Assyrian palace or ancient Rome. Photogrammetry is also used as an analytical tool, and digital topographical models have been combined with astronomical calculations to verify whether or not certain structures (such as pillars) were aligned with astronomical events such as the sun's position at a solstice. Agent-based modelling and simulation can be used to better understand past social dynamics and outcomes. Data mining can be applied to large bodies of archaeological 'grey literature'.
