Left and right of the apse in the Church of Saint Elias (Croatian Sv. Elizeja, sign in local dialect Isei)
This is most likely the preliminary announcement narrated in Pseudo-Matthew. Mary stands outside a building, presumably the Temple, and there appears to be no arriving dove. But there are also new features that start coming into use at this time. The vase in the bottom left has flowers in it, and Mary holds her hand to her breast, as will be the rule in the 14th century and beyond.
