And Bohemian artist Wenzel Hollar etched Landschafts-Kopf in the 17th century:
Is it a portrait or a landscape?

The first few powers of 5 share a curious property — their digits can be rearranged to express their value:
25 = 52
125 = 51 + 2
625 = 56 – 2
3125 = (3 + (1 × 2))5
15625 = 56 × 125
78125 = 57 × 182
It’s conjectured that all powers of 5 have this property. But no one’s proved it yet.
