The usual type is that which you find in East and West – the Virgin holding the child. This is an image of several things and not only the Mother of God as a person. It is an image of the Incarnation, an assertion of the Incarnation and its reality. It’s an assertion of the true and real motherhood of the Virgin.
And, if you look attentively at the ikon, you will see that the Mother of God holding the Child never looks at the Child. She always looks neither at you nor into the distance but her open eyes look deep inside her. She is in contemplation. She is not looking at things. And her tenderness is expressed by the shyness of her hands. She holds the Child without hugging him. She holds the Child as one would hold something sacred that one is bringing as an offering, and all the tenderness, all the human love, is expressed by the Child, not by the mother.
She remains the Mother of God and she treats the child, not as baby Jesus, but as the Incarnate Son of God who has become the son of the Virgin and He, being true man and true God, expresses to her all the love and tenderness of man and God both to His mother and to His creature.
