In the context of this artwork, discuss the Agriculture of the Prehispanic Panel.
The artist illustrates the birth of agriculture in Mesoamerica with four images. Thus, illustrating some of the earliest instances of agriculture in the World, some 10,000 years ago. The wild grass-like image pictured below represents teosintle. This is the grandfather of maize, often called corn. As one can gather from the example of teosintle below, it was small with a few minuscule, hard grains and creating soft, sweet corn, in large cobs, from the original wild grass was a major exercise of observation and patience.Some of the earliest evidence of the domestication of teosinte and other plants has been discovered in caves in the state of Oaxaca.
The image below illustrates a family cultivating the soil, one of the first steps in organizing agriculture. Farming is a group effort and required the move from a hunter-gatherer phase and into small farming communities such as  San José Mogote which is located in the Oaxaca area,
The digging stick being used to cultivate the soil is a uictli in Náhuatl. After the Conquest, with the Spanish language dominating, it was called a coa.
The next image illustrates a man and a woman working the ground with a uictli. The man and woman are working in a milpa.The woman's skirt appears to be woven, a step up from the loosely draped garment of the previous figure. Perhaps it was woven at Monte Alban more than 2,000 years ago.  In addition to the corn growing behind them, there is squash growing at their feet, as seen in the image below, an element of the three sisters method of cultivation.The man has a gourd around his waist. Gourds were used as a container for seeds 8,000 years ago, or longer.
