The Medieval Bestiaries speak of the mother Pelican feeding her chicks with blood from her breast. It is became a popular image of Christ feeding the faithful in the Holy Eucharist. the same ideas lie behind piety that developed in the devotion to the Sacred Heart. In our Sacred Heart chapel there is a window in which the Sacred Heart is depicted, blood pours to the bottom of the window and is caught in the window below in a chalice. I have never been able to photograph it as someone 120 years ago built my house about six foot behind, so it never gets light shining through it as the designer intended.
