the polychrome painted leaded panel with a chequered field and foliate border (by Cottier & Co of London) with a roundel of a displaying eagle to the top section and the pictorial panel featuring the standing Christ figure below,

The symbolism of Christ and Christians as shepherd and sheep is founded on the parables in Luke (15:3-7) and John (10:1-18): 'I am the good shepherd: the good shepherd giveth his life for the sheep.' And to a lesser extent by Psalm 23: 'The Lord is my shepherd; I shall not want."

Depicted above is an eagle. It was a medieval symbol of Christ's Ascension. It is also, more relevantly, the attribute of John The Evangelist from whom the 'Good Shepherd' quote comes.
