In The Beginning--Although the Spanish occupation was the decisive factor defining Puerto Rico's current culture, the island was settled many thousands of years ago by Amerindians. The oldest archaeological remains yet discovered were unearthed in 1948. Found in a limestone cave a few miles east of San Juan, in Loíza Aldea, the artifacts consisted of conch shells, stone implements, and crude hatchets deposited by tribal peoples during the first century of the Christian Era. These people belonged to an archaic, seminomadic, cave-dwelling culture that had not developed either agriculture or pottery. Some ethnologists suggest that these early inhabitants originated in Florida, immigrated to Cuba, and from there began a steady migration along the West Indian archipelago.
Around A.D. 300, a different group of Amerindians, the Arawaks, migrated to Puerto Rico from the Orinoco Basin in what is now Venezuela. Known by ethnologists as the Saladoids, they were the first of Puerto Rico's inhabitants to make and use pottery, which they decorated with exotic geometric designs in red and white. Subsisting on fish, crabs, and whatever else they could catch, they populated the big island as well as the offshore island of Vieques.
By about A.D. 600, this culture had disappeared, bringing to an end the island's historic era of pottery making. Ethnologists' opinions differ as to whether the tribes were eradicated by new invasions from South America, succumbed to starvation or plague, or simply evolved into the next culture that dominated Puerto Rico -- the Ostionoids.
Much less skilled at making pottery than their predecessors but more accomplished at polishing and grinding stones for jewelry and tools, the Ostionoids were the ethnic predecessors of the tribe that became the Taínos. The Taínos inhabited Puerto Rico when it was explored and invaded by the Spanish beginning in 1493. The Taínos were spread throughout the West Indies but reached their greatest development in Puerto Rico and neighboring Hispaniola (the island shared by Haiti and the Dominican Republic).
Taíno culture impressed the colonial Spanish, and it continues to impress modern sociologists. This people's achievements included construction of ceremonial ballparks whose boundaries were marked by upright stone dolmens, development of a universal language, and creation of a complicated religious cosmology. They believed in a hierarchy of deities who inhabited the sky. The god Yocahu was the supreme creator. Another god, Jurancán, was perpetually angry and ruled the power of the hurricane. Myths and traditions were perpetuated through ceremonial dances (areytos), drumbeats, oral traditions, and a ceremonial ballgame played between opposing teams (10-30 players per team) with a rubber ball; winning this game was thought to bring a good harvest and strong, healthy children. Skilled at agriculture and hunting, the Taínos were also good sailors, canoe makers, and navigators.
About 100 years before the Spanish invasion, the Taínos were challenged by an invading South American tribe -- the Caribs. Fierce, warlike, sadistic, and adept at using poison-tipped arrows, the Caribs raided Taíno settlements for slaves (especially female) and bodies for the completion of their rites of cannibalism. Some ethnologists argue that the preeminence of the Taínos, shaken by the attacks of the Caribs, was already jeopardized by the time of the Spanish occupation. In fact, it was the Caribs who fought most effectively against the Europeans; their behavior led the Europeans to unfairly attribute warlike tendencies to all of the island's tribes. A dynamic tension between the Taínos and the Caribs certainly existed when Christopher Columbus landed on Puerto Rico.
To understand Puerto Rico's prehistoric era, it is important to know that the Taínos, far more than the Caribs, contributed greatly to the everyday life and language that evolved during the Spanish occupation. Taíno place names are still used for such towns as Utuado, Mayagüez, Caguas, and Humacao. Many Taíno implements and techniques were copied directly by the Europeans, including the bohío (straw hut), the hamaca (hammock), the musical instrument known as the maracas, and the method of making bread from the starchy cassava root. Also, many Taíno superstitions and legends were adopted and adapted by the Spanish and still influence the Puerto Rican imagination.
