The painting most probably comes from Byzantine Tradition as we can see the use of gold a well-known attritube of most of the Orthodox artist in expressing their views or faith.
The symbol ICXC in the middle of the painting with overline make certainty that this artwork belong to Eastern or Byzantine Tradition and there's no Muslim iconography here as it would be an obvious contradiction to their upheld Tradition.
"In Eastern Christian tradition, the monogram ΙϹΧϹ (with Overline indicating scribal abbreviation) is used for Ἰησοῦς Χριστός in both Greek and Cyrillic tradition."
The artwork depicted the five (5) characters who had the important role in the Drama of Man's Salvation.
Abba Father the source of Authority & Graces.
The Begotten Son Jesus the source of the Holy Eucharist
And the Holy Spirit in the form of the dove, the source of Sanctification the giver of Life.
Plus, I saw the Ark of the Covenant meaning Mary the chosen Woman from eternity is also depicted here and we will elaborate below as part of the hidden character here.
In addition, Lucifer is also depicted here below the Throne of God as wing angel in a circle form signifying resemblance to God's likeness in power.
Note : Both the foot of the Father and the Son was shown by the artist in the same color tone & sandals meaning both of them had set their foot on their creation.
The painting title can be name as " The Abba Father Divine Plan of Salvation"
Further deciphering the image we can describe them as follows;
The Abba Father wears a white garment signifying clothe in Holiness or Light. His left hand contain the written Divine Plan for the Salvation of Mankind and the right hand raise in a familiar hand symbol of Jesus having the 2 fingers, others interpret this as 2,000 years, meaning only the Abba Father knows the hour. The Abba Father although He is the one seated on the Throne His halo is represented by a lot of triangle formation representing the Wisdom of the Holy Trinity.
Jesus the Begotten Son is clothe in gold representing purity and not clothe with the Light or Holiness like the Abba Father as Jesus will come in the form of man devoid of Majesty and Glory but will be born sinless or pure. Noticed the artist emphasis of the Abba Father and the Begotten Son had the same color tone or body essence meaning same substance or nature. Jesus halo represented the symbol of Cross signifying His Redemptive mission was already foreordained in Eternity before He came into this world.The "Way of the Cross"(Genesis 1:1).Noticed also the Hand of Jesus holding a white circle, a symbol that represents the Holy Eucharist that will be the source of Eternal Life in John Gospel Chapter 6 Bread of Life discourse.
The Holy Spirit was represented by a dove like when it came down to Jesus to dwell with Him in the Baptism in the river Jordan. The halo of the dove is represented with gold meaning His Holiness is the same nature with the Father and the Son depicted in their bodies but the Holy Spirit is white dove representing that She was clothe with the Holiness or Light same as the Abba Father. Since the white dove has no body, how can She manifest Her existence on earth? The mystery was answered by the blue & white colored circle and will interpret it below in the hidden character title.
Hidden Characters :
The Hidden Character and symbols here is the Ark of the Covenant expressed by the artist by putting the two wings cherub on both side. This is supported by Jesus hands on the white circle representing the manna or the Holy Eucharist in the New Testament. Mary role & character was hidden here in the form of the blue circle as we know Tradition called Mary the Lady in Blue and the white dove was inside the blue circle meaning Mary the Lady in Blue was indwelt by the Holy Spirit. St.Kolbe called this "quasi-incarnate" in comparison to Jesus which is known as the Incarnated Logos. The white circle that the hands of Jesus holds symbolizing He is the one offering the sacrifice but it is connected to the blue circle as the Mary is the Mother of the Eucharist the flesh or "body & blood" of Jesus comes from Mary."
Lucifer is included here, the artist depicted Lucifer below the Throne as wing angel in circle signifying Lucifer perfection of beauty among the Heavenly Angels and likeness of power to God. Lucifer was "anointed" by God to guard the Holy Mountain or the Throne of God. (Ezekiel 28:14-ff) described Lucifer perfection that made him feel that he is like God. But Lucifer only bear the Light of God or was "anointed" to guard the Throne of God. Lucifer is only a cherub but in Book of Ezekiel, Lucifer was able to surpass the power of Seraphim thru his anointing able to walk in the fiery stones. Seraphim is known as the fiery angels the burning ones that is much closer to God's Throne compare to Lucifer which is only a cherub.
NOTE: The artist colored the circled wing angel below the Throne brown denoting earthly color. Biblically, Lucifer after his fall was cast down to earthly realm. A color contrast with the color of wing cherub on left & right side is artist way of conveying the difference of Angelic glory.And size difference denotes wing cherub was glorified and Lucifer shrink in size denotes demotion.
In closing, the artist perfectly describes what is the "Divine Plan of God"existed in eternity represented by three concentric circles symbolizing the Holy Trinity inside the Third Heaven. We can see that the artist included the Ark of the Covenant here plus Lucifer being the bearer of God's Light or guardian of God's Throne in the Holy Mountain. The Five Characters (Abba Father, Jesus Christ, Holy Spirit the "another Advocate & Spirit of Truth, Mary the Theotokos and Lucifer which is created good and bestowed with perfect gifts & anointing) are the main actors in the Drama of Man's Salvation.
