All of whom have analogous Norse, Celtic pantheon (sorry cult of Mithras, Romans didn’t influence much there until the Catholics).
Then onto the symbols themselves: Mermaid/ centaur is seen in almost identical fashion around the world including the Americas, especially Mexico and Peru.
The V-rod appears to be a bent arrow superimposed on a crescent; it is assumed to be a symbol of death: Another object commonly inscribed on Pictish stones is the mirror, often paired with a comb.
The comb and mirror are symbols of female wealth and prestige, and usually denote a woman’s memorial, although they are also heavily associated with mermaids: All symbols from the dawn of time have had layered meaning only understood by different levels of initiates.
Men, in contrast, are hypothesized to be most attracted to women in their reproductive prime, which tends to be when they are younger. Women’s preferences, on the other hand, hold relatively constant across their lives, not going more than a few years below their own age (extra-credit if you can identify the "cougar zone" in this figure), but women remain keen on men up to 10 years older than themselves. However, younger men (i.e., in their 20’s) tend to be married to someone of a similar age, but as they get older their wives get younger.
For example, by their 50’s the average male has a wife who is 10 years younger than him.
The v rod and z rod are both masonry tools amongst other things previously mentioned in the comments, various cycles ect.
The v being a compass and z being like a spacing rule(ancient tape measure) Many of you were right in recognizing the arrows as common symbols for time, same with the serpent.
I was told and I agree that this is the goal of the initiate to unify man’s polar nature/ polarity consciousness.Now that we don't need to do that we're going for younger men.Literally, we are choosing physical attraction over security because we now have options that never existed for us before.After the fifth century, most Picts converted to Christianity, and most of their carvings reflect this change; many of the so-called “Celtic crosses” dotting England and Scotland are in fact Pictish stones.Most unusual, and most identifiably Pictish are the enigmatic symbols known as the “V-rod,” “Z-rod,” and “double disks,” all named for their unusual shapes.A common rule of thumb, at least on the internet, is that it’s okay to be interested in someone “half your age plus seven” years.
