I understand , if in a red dress and blue veil - it's Madonna , and if the baby without any clothes means - Jesus Christ <! - ~ 1 ~ ->
Do not worry, they're all different on the face ?
But who is this lady ?
Under the proposed dress code " red dress - blue cape " is not like <! - ~ 1 ~ ->
Irina S! All the pictures you have the author's name , which determine who is depicted .
And the images are backed up by halos .
 But I think that is wrong to call any image an unknown woman with a child - "Madonna"

I did not want to argue with you , and I led the first three images caught - they are a huge number of titles and authors with or without them.
And you know for sure what was the face of the Virgin and Jesus Christ? ?
Of course people are all different - different artists, different eras and different countries. Read about the iconography of the Virgin Mary in the Orthodox and Catholic (which refers to the specific case ) tradition.
Good luck ! <! - ~ 1 ~ ->

Thanks for the tip , Irina S, you are so kind <! - ~ 1 ~ ->
I read . It turns on the icon of the Virgin and Christ always designated by appropriate inscription . (You know it! and say <! - ~ 1 ~ ->
But as the picture which shows a mother and her son , understand that this is the Mother of God, if the author does not have it in the title ?
Well, halos , of course , but what else?

Most of the paintings did not give the names of authors (such as your picture from London), and art.

Before you are not an icon.

P.S.
And do not call the image of Christ portraits

In fact, in Western iconography mafory portrayed in blue , but occasionally the scene of the Annunciation - red (red color then - a symbol of the Holy Spirit in the image of the Archangel Gabriel , and in this case, the Archangel Gabriel is not represented , but instead show a dove - the symbol Holy Spirit).

And as in ancient iconography of Our Lady of mafory wrote hocks (dark red with a violet tinge, near the ancient purple ), on the edge of the cloak is the fringe of the three gold stripes, symbolizing the Holy Trinity , and three gold stars (in the forehead and shoulders ), meaning "three virgins " Mary, povoy - scarlet color, tunic - blue.

redbor, then what your principles? image of Madonna and Child in a Catholic world are seen as the Mother of God with Jesus, and you continue to assert that it is not tak.Irina and Kiril explain to you, and you are at it again ....

Good, good.
Sorry.

If you want to call the woman depicted the Virgin Mary, - please.
<! - ~ 1 ~ -> Did I somewhere so called?
