Smells like ancient society: scientists find ways to study and reconstruct past scents
Past scents can be recovered from scent archives by extracting molecules using a variety of different methods. With successful detection and identification of the molecular composition of samples, ancient sources of smell can then be identified. Credit: Nature Human Behaviour (2022).

Millions of people have suffered the loss of smell due to COVID-19. The world of scent is different for people who have avoided the new coronaviruses because of the masks that protect them. The loss of olfaction has highlighted the importance of smell in how we perceive and navigate the world, and underscored the connections between olfaction and mental and physical health.

The human experience has always included scent, but the past has been mostly odorless. Most smells come from organic substances that decay quickly, making it hard for archaeologists to investigate thousands of years later. The smellscapes of the past can be brought back to life and used to study past experience, behavior and society.

The fact that history records expeditions of discovery, wars, and long-distance exchange to acquire materials with strong olfactory properties makes it difficult to track scent in the deep past.

The use of odorous and aromatic substances can contribute to knowledge about many aspects of the past, including ritual, perfumery, hygiene, cuisine, trade and commerce. Ancient scents can provide insight into more general aspects of the past, from social hierarchy and social practices to group identity, because scent is part of how we experience, understand and navigate the world.

Scent data can be contextualized within the framework of relevant historical texts and visual representations, as well as the archaeological and environmental records. Connecting these different sources of information enables the reconstruction of critical aspects of ancient lifeways and society (indicated by arrows emerging from the blue circle). The icons in the outer area of the figure represent examples of some of the themes that can be addressed through this approach (grey boxes indicate broad headings).

Professor Nicole Boivin, senior author of the study and Director of the Department of Archaeology at the MPI Science of Human History notes that scent is a powerful and underappreciated aspect of human experience.

Using only traces of scented substances preserved in archaeological artifacts and features, and novel methods are revealing the powerful odors that were a feature of ancient lived realities, and that shaped human action, thoughts, emotions and memories.

By linking new data with information from ancient texts, visual depictions, and the broader archaeological and environmental records, researchers stand to open up new aspects of the ancient world. The authors of the new paper hope that more research into the rich and varied smellscapes of the past will provide insight into the sensory worlds of long ago.
