The Adoration of the Holy Trinity
Albrecht Dürer, 1511
Kunsthistorisiches Museum Vienna
The work was painted in 1511 for Matthaeus Landauer and there is more about it at the link Adoration of the Trinity.
The painting is a wonderul image of the Communion of Saints, of which we are called to be part. Let us pray that we may indeed become that which we are called to be.
