Islam emerged in the seventh century in what is today Saudi Arabia. The traditional account maintains that God revealed his will to Muhammad (AD 570?–632) in a series of revelations dictated by the angel Gabriel over roughly 20 years. These revelations, codified and put into writing after Muhammad’s death, compose the Qur’an, accepted by Muslims as the Word of God. The Qur’an is said to be God’s definitive revelation, the culmination of earlier revelations to numerous prophets, including Jews and Christians (called “People of the Book” in the Qur’an). Muhammad is said to be the last and greatest of the prophets.

The Olmecs flourished during Mesoamerica's formative period, dating roughly from as early as 1500 BCE to about 400 BCE. Pre-Olmec cultures had flourished in the area since about 2500 BCE, but by 1600–1500 BCE, early Olmec culture had emerged, centered on the San Lorenzo Tenochtitlán site near the coast in southeast Veracruz. 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 Olmec's 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.
