As I was writing the post about St Christopher, I looked for pictures and I found the picture displayed in the St Christopher post. I like the portrayal of St Christopher and the Christ Child, but I wondered who are the saints on the right and left.
Because the picture is actually the center panel of a triptych (Moreel Triptych), I was able to look up info on it and identify the Saints as Sts Gilles and Maurus. I know that St Gilles was a hermit and he took an arrow for a beloved deer who kept him company, but that's about all I know. I don't know anything about St Maurus.
I will probably look up these two later, but if you are like me you have to know who the saints are and what is significant about their iconography.
