Very little is known about the history of the Diquis region before 1000 BC, though culturally it appears to have formed part of the Greater Chiriquí region, which takes its name from the province in southwestern Panamá. Archeologists date the famous lithic spheres from sometime between 1000 BC and 500 AD; between around 700 and 1600 AD the Diquis began fashioning gold pendants, breastplates, headbands and chains, becoming master goldsmiths within a hundred years or so. Between 500 and 800 AD drastic changes occurred in the culture of the Diquis. Archeologists attribute them to the impact of the arrival of seagoing peoples from Colombia or possibly the Andes – a theory borne out by their metates and pottery, which show llama or guanaco figures, animals that would have been unknown on the isthmus. In the Diquis’s own artisanry, both the ingenious – often cheeky – goldwork and the voluptuous pottery display a unique humour as well as superlative attention to detail.
The Diquis were in a state of constant warfare among themselves and with foreign groups. Like the Chorotegas to the north in Greater Nicoya, they seem to have engaged in sacrifice, ritually beheading war captives. Huge metates unearthed at Barilles in Panamá show images of these rituals, while smaller crucible-like dishes – in which coca leaves, yucca or maize may have been crushed and fermented – suggest ritual inebriation.
The indigenous peoples of Zona Sur first met the Spaniards in 1522 when the cacique of the Térraba group graciously hosted Captain Gil González for a fortnight. González was on his way from near the present-day Panamá border, where his ship had run aground, to Nicaragua. Despite infirmity (he was in his fifties), he was walking all the way. The Diquis seem to have declined abruptly after this initial contact, most likely felled by influenza, smallpox, the plague and other diseases brought by Spanish settlers.
