I won't go into detail a lot but this looks like a commemoration to creation. This is not a context that is taught in mainstream you can tell this is an expression that comes from outside of mainstream within the societies that I am apart of. Often things are made like this to remind us of the knowledge or just as expressions of intent. When something means a great deal to us, we will create commemorations of our own and this is what I see as a form of spirituality. Mostly to remind of divine creation.

You will notice the letters are greek and the meaning of them in this context is mathematical and relates to the construction of the universe. The top part suffice it to say is the alpha and omega, or beginning and end of everything. Together with the central number of creation the golden ratio. This is very important to creation and consists of it's main building blocks if you will.

The bottom part is to do with the expression of those building blocks. For instance ones individual vibration as it relates to the cosmos. And ones place within that structure and the means avaliable for a persons potential. The means of 'doing'.

The planets here are a testimony to these building block as it relates in this context to the 'music of the spheres' (pythagorean concept). The different vibrations that make up creation as they are expressed through those planets, in our solar system.

That ship you see, refers to the ever present active intelligence and design of those within the free comos, and could be seen to represent life and mobility, freedom to 'build'.

The mathematical depiction in the left hand corner is an expression of dimensions of the universe as it relates to time and space. In this instance it completes the message of what appears to be an ode to creation. Whoever created this perhaps wanted to convey a sense of timelessness and enternity of the potential within us, for whatever reason.

Hope this helps.
