That's amazing and beautiful, and I can't imagine doing it with a quill in an inadequately heated monastery scriptorium on an Atlantic island in November.

But it was done that way regardless.

Here's the Lindisfarne Gospels.

Here's the Book of Kells.

Stunning sunset! This happens because of a phenomenon called Rayleigh scattering: cirrus clouds scatter the longer, red wavelengths of light and give the sky an orange or reddish hue | source

Dirty thunderstorm

A dirty thunderstorm (also volcanic lightning, thunder volcano) is a weather phenomenon that is related to the production of lightning in a volcanic plume.

A study in the journal Science indicated that electrical charges are generated when rock fragments, ash, and ice particles in a volcanic plume collide and produce static charges, just as ice particles collide in regular thunderstorms.

Volcanic eruptions are sometimes accompanied by flashes of lightning. However, this lightning doesn’t descend from storm clouds in the sky. It is generated within the ash cloud spewing from the volcano, in a process called charge separation.
