Pollen analysis, also known as palynology, was developed in 1916 by Swedish geologist Lennart von Post, and is the study of fossilized pollen to reconstruct the conditions of past climates and vegetation. Because the practice encompasses many scientific fields (geology, ecology, climatology, etc…), it has been considered one of the most valuable dating methods in archaeology. Palynology is mostly utilized to determine changes in vegetation over time, which further aids in chronology, the ordering of events in which they occurred in time.
There are certain types of archaeological sites that prove most fit for pollen analysis to be conducted. Larger basins are most ideal because they usually have more accumulated sediment with longer cores, meaning that a sample with a larger time frame would be taken. Acidic peat bogs and lake beds are also beneficial in the preservation of pollen, and it is most poorly preserved in open sites or exposed areas. There are some other limitations. For instance, constructing a completely accurate account of past climates and surroundings is not possible.
Even with newer research methods being developed relatively often, palynology proves invaluable in present-day archaeology. Researchers applying the method in Cairo, Egypt have discovered evidence that there was a branch of the Nile River, now dried up, that aided in the construction of the Pyramids of Giza. The archaeologists sampled sediment cores, and in their matrixes, recovered fossilized pollen. After further analysis, the pollen was determined to be from local grasses and marsh plants that boarded the edges of lakes and rivers. Because of this, it is believed that water levels of the Nile River’s Khufu branch in around 2550 B.C.E. were high enough to transport construction materials such as limestone and granite to the sites of the pyramids.
This application of pollen analysis has also aided archaeologists in their research about how the ancient Egyptians traveled using the Nile River. Before the use of palynology, researchers did not have a complete understanding of the environment and surroundings of the Nile River and any land involved. It has greatly contributed to the further understanding of the Nile’s floodplain 4,500 years ago, and the further investigation of hypotheses such as the “fluvial-port-complex” hypothesis. This proposes that the ancient Egyptians, in order to transport materials, created a canal from the Khufu branch to the site where the pyramids were being constructed. There is evidence that they dredged basins to the bottom of the Nile River and used seasonal flood waters as a hydraulic lift to transport heavy materials.
Without pollen analysis, archaeologists, much like those working in Cairo, would not have much understanding of former environments and landscapes. Even though it has some limitations, it still proves extremely useful in present-day archaeology in regards to aiding in chronology and research of past landscapes.

How does understanding the environment of a particular place and time through techniques like palynology give us insight into the experiences of a particular culture in that place and time?
Understanding the environment of a particular time and place gives us insight into past cultures, such as what environmental adversity they faced and how they responded to it. Also, it is possible to determine the culture’s diets and what natural resources were present at the time.
