The Zapatera Archipelago in Nicaragua consists of Zapatera Volocano and 8 islets, all sitting lazily in sun drenched Lake Nicaragua. One of these islets is Isla del Muerte, or Island of Death. Something to do with human sacrifices.
The petroglyph's on these islands are simply amazing and well worth the effort to get here.
Another term for petroglyph is "rock art". Makes sense when you see the deeply etched markings on flat rock faces that look like ancient graffiti.
The etchings have various styles and shapes. There are literally hundreds of them. I can imagine someone a lot of years ago trying to depict their world as they saw it. Maybe to them plants and animals, and for that matter, humans, did look fanciful and other-worldly. No kidding, some of these creatures look like they have space helmets on, with feathers stuck all over the place. An ancient version of a very bad hair day.
I like imagination. Combined with art, it makes for some interesting mind stretching. And, combined with the enormous amount of effort it must have taken to actually carve these markings into solid rock, I am duly impressed.
