How does Andrey Rublyov's Three Angels Visiting Abraham (Old Testament Trinity) exemplify the style and iconography of Late Byzantine art?

What will be an ideal response?

The ideal ; Answer should include:
1. Andrey Rublyov's Three Angels Visiting Abraham (Old Testament Trinity) is an icon that depicts the Trinity, and Rublyov tackled this challenging theme by showing three identical divine individuals, or angels, from a story in the Hebrew Bible in which Abraham's wife Sarah entertained three strangers who were in fact God.
2. Tiny images of Abraham and Sarah's home and the oak of Mamre can be seen above the angels, and, on the table, the food the couple offered to the strangers becomes a chalice on an altar-like table.
3. The icon demonstrates how Late Byzantine artists created an ideal geometry to evoke a heavenly realm in the use of the circle-most apparent in the halos-that form the basic underlying structure for the composition.
4. His figures also highlight the use of Byzantine conventions, such as salient contours, elongated forms, and a limited number of figures to capture a sense of the spiritual.
