Albert Mackey,
The Symbolism of Freemasonry — Chapter XXVI
(1882)
“ Now, the attainment of this moral and intellectual condition supposes an elevation of character, an ascent from a lower to a higher life, and a passage of toil and difficulty, through rudimentary instruction, to the full fruition of wisdom. This is therefore beautifully symbolized by the Winding Stairs; at whose foot the aspirant stands ready to climb the toilsome steep, while at its top is placed "that hieroglyphic bright which none but Craftsmen ever saw," as the emblem of divine truth. ”
