F_2_11 — Ancient Spice and Incense Routes: Aromatic Trade Networks

The trade in aromatic substances — frankincense, myrrh, cinnamon, cassia, pepper, cloves, nutmeg, camphor, sandalwood, spikenard, and dozens of other plant-derived resins, barks, seeds, and oils — constitutes one of the

F_2_03 — Sub-Saharan African Maritime and Trade Networks

Sub-Saharan Africa was deeply integrated into global trade networks for millennia, challenging Eurocentric narratives that portray the continent as isolated before European colonization. The Indian Ocean dhow trade conne

F_2_04 — Obsidian Trade Networks: Archaeological Tracers of Ancient Exchange

Obsidian — naturally occurring volcanic glass formed when felsic lava cools rapidly — was one of the most valued materials in the prehistoric world. Its conchoidal fracture produces the sharpest edges known (thinner than

F_4_13 — Glass Production: Origins, Trade, and Technology Transfer

Glass is one of the earliest synthetic materials, with origins tracing to faience (glazed quartz) production in Egypt and Mesopotamia by ~5000 BCE and true glass beads appearing by ~3500 BCE. For over two millennia, glas
