Yesterday my dad had his boat lifted out of the water like he does every autumn to keep the ice from damaging it. I hadn’t seen the lift they used before: it’s a remote-controlled motorised thing, fast and nifty. Note the yellow control box.
This reminded me of a fairly common motif in Bronze Age rock art, the boat carrier. Boats are extremely common, and sometimes you’ll find a guy lifting the boat, crew and all. I think this is probably a depiction of the Sea God. But it may also be a human lifting a wooden ship model. We have a few bronze figurines that look like they may have adorned such models. Or it may be both: people perhaps played the role of the Sea God in cult drama, brandishing ship models.
One of the most elaborate boat carrier images is the Brandskog ship near Enköping.
