They were the first Mesoamerican civilization, and laid many of the foundations for the civilizations that followed . Among other "firsts", the Olmec appeared to practice ritual bloodletting and played the Mesoamerican ballgame, hallmarks of nearly all subsequent Mesoamerican societies . The aspect of the Olmecs most familiar now is their artwork, particularly the aptly named "colossal heads". The Olmec civilization was first defined through artifacts which collectors purchased on the pre-Columbian art market in the late 19th century and early 20th century . Olmec artworks are considered among ancient America's most striking . </P>
