By 400 BC, Persian engineers had invented a refrigerator in the middle of the desert. Ice was imported in large quantities from the nearby mountains during the winter months and stored in Yakhchal. These are conical buildings made of a special insulating mixture of clay, goat's wool, and egg white, which prevent the penetration of daytime heat.

Over 3,000 years ago, the Assyrians developed a remarkably advanced underwater technique, as illustrated in this ancient relief. It shows Assyrian soldiers using goatskin bags filled with air to help them breathe while submerged-a clever early example of diving gear.

In 1822 people spotted a stork in Klütz, Germany with an arrow through its neck. The spear was described as one with “a broad iron tip attached with sinews” and “very fine-veined tropical wood,” suggesting that the bird was likely impaled while wintering in the “Upper Nile Region”—modern day Sudan—where such spears were commonly used in hunting and warfare. This convinced zoologists that birds migrated in the winter, and disproved other theories such as underwater hibernation, or metamorphosis into other animals.

Amazingly, there have been 24 subsequent recorded storks that have successfully migrated to Europe with an African spear embedded in their flesh.

This wooden elk head was found in a bog in Lehtojärvi, Rovaniemi, when digging a ditch in 1955. Based on the joints carved into the elk's head, the object was probably a boat figurehead. Elk-head prows are a common motif in prehistoric rock art and can be clearly identified in about 12% of prehistoric boat depictions discovered in Finland. Depicted here is one of the most obvious examples of an elk-head prow, the boat painting from Patalahti, Asikkala.

The Lehtojärvi elk head (KM 14189:1 🔗) has been dated to about 8,000 years old, placing it in the Mesolithic Stone Age. It was originally painted with red ochre (the same iron oxide pigment used in Finnish prehistoric rock art) and waterproofed with a greasy substance.

The elk (Alces alces) was of extraordinary importance to northern populations for several millennia, being not only the most important game animal in the boreal forest zone, but also an animal of notable symbolic significance. Researcher Ville Mantere presents the argument that there were two fundamental reasons for producing elk representations in rock art and on artifacts: to gain success in hunting and to guarantee the reproduction of elks for hunting.

Another central argument is that the elk cow embodied the “game ruler” or “animal master spirit” of elks, which had ultimate control over not only rebirth and fertility, but also hunting success. The focus on the elk cow as a life-giver seems to have been a key theme that persisted for several millennia in Northern Europe.

Mantere further argues that elk figures in rock art represent elks as individuals, and that figures depicted at ordinary rock art sites signalled the presence of humans in the landscape and their relationship to the local elks, whereas those found at large rock art concentrations were linked to meetings between hunter-gatherer groups.
