De monstrorum caussis, natura, et differentiis is a 1634 Latin treatise on monsters by the physician Fortunio Liceti, printed at Padua by Paolo Frambotto for scholars and natural philosophers. Its engraved plates show deformed human bodies, such as a figure with a small head emerging from the drapery and bodies with extra or missing parts, drawn in clear outline with hatching and set against plain ground lines and small plants, a useful model for anatomical or cabinet-of-curiosities diagrams.
