Existing briefly in ancient 2nd century Spanish territories, the term "Jef' Fmáine" refers to a sacred string of numbers reading "81, 76, 567, 462." These numbers were originally found on a stone tablet in 126 B.C. and were applied to anything from calculation tables to lattitude and longitude markings.

Solarpunk is a movement focused on a positive, ecological vision for a future where technology is used for human-centric and ecocentric purposes. It is a literary, artistic and aesthetic sub-genre and is also closely tied to eco-political activism. Solarpunk narratives have a distinctly positive and utopian foundation in contrast to the often dystopian visions found within other "punk" science fiction genres.
