Analysis of Petroglyphs and Vessel Depictions
A new study compares rock carvings of boats from northwestern Iberia with those from Scandinavia, uncovering shared features that suggest maritime connections across Europe more than 3,000 years ago. These engravings date to the Late Bronze Age (1300–800 BCE). The similarities indicate that technology, symbols, and ideas were exchanged through Atlantic networks, rather than being coincidental.
The research examines boat carvings from northwestern Iberia alongside Scandinavian rock art. Over 20,000 Bronze Age boat images have been documented in Sweden and Denmark. In Iberia, maritime depictions are rare, and the recently analyzed examples come from northern Portugal and southwestern Galicia. The Iberian carvings include specific design elements such as:
- decorated ship ends
- bird-shaped or S-shaped terminals
- oars
- possible steering devices
- shapes that may represent sails, rigging, or sail-related equipment
Some carvings depict larger vessels rather than simple canoes.
Timeline and Cultural Connections
The study dates the Iberian carvings primarily to the Late Bronze Age, around 1300–800 BCE. This chronology is based on comparisons with Scandinavian boat images found on dated bronze objects, stone slabs, and other contexts. Northwestern Iberia was positioned between metal-rich inland regions and the sea. Some Iberian panels feature solar crosses or segmented circles alongside boat depictions.
The authors emphasize that such similarities are unlikely to be accidental or based solely on vague impressions of foreign ships. They suggest that either sailors from outside Iberia carved some of the images themselves, or local communities adopted and adapted maritime technologies and symbols. 'The carvings may belong to the same world as long-distance metal exchanges,' the researchers note.
The study also argues that these boats were likely more than practical depictions of transport. This connection is significant because Scandinavian Bronze Age rock art has long been linked to concepts of solar journeys. However, this does not imply that northwestern Iberia and Scandinavia shared a single religion.
This research highlights the importance of maritime links between different Bronze Age cultures, suggesting that interactions among communities may have been more complex than previously thought. The exchange of technologies and ideas likely occurred through networks spanning vast areas, reshaping views on the development of civilizations in Europe. The discovered similarities in techniques and symbolism may point to deep cultural ties among people living on different shores of the Atlantic.
These findings not only highlight the maritime connections of ancient cultures but also resonate with other recent discoveries from the Bronze Age. For instance, researchers have identified unique rock footprints that belonged to specific individuals, shedding light on the personal histories of those who lived during this era.
