What is depicted on the gate shown in episode 63 of Brotherhood?


I'm looking to get a tattoo of the gate depicted in episode 63, but I don't
know what it is that I'm looking for. I know that there are two gates, and one
of them is "The Tree of Life".

I'm looking for the other one, depicted in this screenshot from episode 63 at
16:46:

What is depicted on the second gate?




There are three different gates in all.

The first one (Ed's) is the so called "tree of life" described in [this
question](https://anime.stackexchange.com/questions/21923/what-is-this-huge-
symbol-on-the-door-in-the-truth-realm-and-in-neon-genesis-evan).

The gate you are looking for is the second gate (Al's), which is the European
Alchemical scheme depicted in George Ripley's _Marrow of Alchemy_ , based off
the Kabbalah's Tree of Life and Kundalini's chakra system, which is probably
derived from Samuel Norton's [_Catholicon
Physicorum_](https://i.stack.imgur.com/qQ0b3.jpg).

The third gate ("Truth's"/Mustang's) does not appear to be derived from known
alchemy symbology from real life, but it share's similarities (two
intersecting triangles) to the tattoo on Riza's back, which is related to
Flame Alchemy.
