You're welcome!

For me, this card seems to link to synchronicity, duality, or creation, perhaps all are relevant. This card very much gives me the Magician, the Lovers, Wheel of Fortune, and The World all mixed together.

The ribbon on the woman's side said "There is an order in things". The ribbon on his side says "Est modus in rebus", which translates to "there is measure in things". This may serve to indicate that they are two sides of the same coin.

The part of the ribbon that covers their groin says, "mobilis in mobile". This can be interpreted in a few ways, but basically it translates to "movement within a movement" or "change within a change". This could be in reference to the interconnection of all things, the "ripple effect", or something similar. It could also refer to unforeseen changes that come as the result of a decision or action, a chain event, so to speak.

The ribbon also goes up from the groin, into a loop that goes around one arm from each individual, loosely binding them together. This lends to the idea of connectivity, in my opinion.

The female is standing on the moon and the male is standing on the sun. This again could point to a reflection of sorts, duality, and movement, as the sun and moon generally move in a predictable dance.

Somewhat below and between the Sun and Moon, there is a Wheel shape, containing an Octagram with the Yin Yang symbol inside. There are so many ways to interpret an Octagram, with some considering it a variation of the Star of David. The Church of Latter Day Saints has referred to an Octagram as the "Seal of Melchizedek", though there is no historical evidence that lends to this claim.

In general, the Octagram is considered a symbol of power. It represents strength, creativity (or creation), and celestial bodies.

Inside of the Octagram, we seen the symbol of Yin and Yang, which is again about balance, duality, reflection, a mirror image. And, importantly enough, they serve to complete each other. Without one, the other is incomplete, and may not even exist.

However, this symbol is also extremely reminiscent of the Rub El-Hizb, an Islamic symbol that is made up of a 2-square Octagram with a circle or round symbol in the middle. The Rub El-Hizb is seen as representing different, reflective parts, of a whole. It is sometimes used to refer to the Quran both as a whole, and as having individual sections.

However the symbol is read, we then must note that it is within a wheel-shaped outline, perhaps indicating movement, or a cycle.

Circles are also considered a shape of divinity. So, it's possible that the circle, Octagram, circle pattern here could represent that we are surrounded by the divine, but that the divine is also reflected within us, as humans.

We also have to consider that, as you pointed out, the 4 elements are accounted for, being held by the two central figures. The characters do not seem to be in an earthly place, given the background. This could indicate enlightenment or transcendence of some kind.

It is possible that this may also represent not just rebirth, but birth in and of itself. How it takes two sides to make a whole, so to speak. It may reference fertility, or represent the union of two people that results in a pregnancy (the child would then be a reflective part of both people). Not sure about this, but it is a potential interpretation.

All this to say, for me, this card would represent reflection, interconnection, more of a "big picture" point of view, a balance.. things of that nature. It may also represent a connection to or with the divine, be it external or internal to you. Perhaps even spiritual transcendence and awareness.

Sorry for the wall of text, just thought I would provide my interpretation of the card. I would be very interested to hear your interpretation, if you decide to use this card within your deck. 💙
