Dürer, Christ among the Doctors
Oil on poplar panel, 26 × 31 in. (65 × 80 cm.)

Jesus counts on his finger, a symbol indicating he is expounding the Trinity. He speaks without recourse to the written materials presented to him, possibly reflecting an episode in chapter 15 of the Infancy Gospel of Thomas where the boy Jesus explains the scriptures without having read them on his first day at school.
The doctor on the left wears on his forehead a passage from the Torah, as is prescribed in Deuteronomy 6:8. The anti-Semitic caricatures left and right of Jesus are most regrettable.
