Short Thoughts…
The painting to the left is The Childhood of Pico della Mirandola by Hippolyte Delaroche, 1842, Musée d'Arts de Nantes and the tarot card to the right is the Aeon Card from the Thoth Tarot deck.
Could this child be giving the sign of silence?
You see a child doing the same on Crowley's Aeon card which replaced the Judgment card. SHIN is on the Judgement card, as well the Aeon card.
Note the baby's hand resting on his shin.
