Claude Mellan (1598-1688) was a french engraver that I consider as a kind of god in the chisel ingraving (which is, in my opinion, the most pain in the ass technique of ingraving).
This guy must have woke up one morning, and told himself, “hey, what if I was ingraving a human face full of details with a single line in spiral. Such a good idea, let’s do it.”

So, the sudarium of Saint Victoria (1649) :

And a close up :

This ingraver also worked on images of the moon. It is funny to compare his images based on his observations through a telescope made with lenses provided by Galileo

with the photographs we can produce now with our so very powerfull technology.

If you want to read more about it, it’s over there.
