Fr. Sieger Koder, St. Francis Celebrates Nativity in Greccio, fresco in Chapel of St. Francis in Ellwangen, Germany, shamelessly pinched from here
Leaving this image a little too large for the frame so you can notice the hidden eucharist in this depiction of St. Francis creating the first nativity scene. Here's a bit more about that. This seemed like a fitting note on which to end the 12 Days -- with the reminder that the mysteries of these days are made present to us in the Eucharist.
Also: this is several days late for the feast of the Holy Innocents, but I found it achingly beautiful.
And: January is the month of the Holy Name of Jesus.
