Arthur E. Waite - The Pictorial Key to the Tarot :
A stately figure, seated, having rich vestments and royal aspect, as of a daughter of heaven and earth. Her diadem is of twelve stars, gathered in a cluster. The symbol of Venus is on the shield which rests near her. A field of corn is ripening in front of her, and beyond there is a fall of water. The sceptre which she bears is surmounted by the globe of this world.
She is the inferior Garden of Eden, the Earthly Paradise, all that is symbolized by the visible house of man. She is not Regina coeli, but she is still refugium peccatorum, the fruitful mother of thousands.
There are also certain aspects in which she has been correctly described as desire and the wings thereof, as the woman clothed with the sun, as Gloria Mundi and the veil of the Sanctum Sanctorum; but she is not, I may add, the soul that has attained wings, unless all the symbolism is counted up another and unusual way.
She is above all things universal fecundity and the outer sense of the Word. This is obvious, because there is no direct message which has been given to man like that which is borne by woman; but she does not herself carry its interpretation.
In another order of ideas, the card of the Empress signifies the door or gate by which an entrance is obtained into this life, as into the Garden of Venus; and then the way which leads out therefrom, into that which is beyond, is the secret known to the High Priestess: it is communicated by her to the elect.
Most old attributions of this card are completely wrong on the symbolism - as, for example, its identification with the Word, Divine Nature, the Triad, and so forth.
P. D. Ouspensky – The Symbolism Of The Таrot :
I felt the breath of the spring, and accompanying the fragrance of violets and lilies-of-the-valley I heard the tender singing of elves. Rivulets murmured, the treetops rustled, the grasses whispered, innumerable birds sang in choruses and bees hummed; everywhere I felt the breathing of joyful, living Nature.
The sun shone tenderly and softly and a little white cloud hung over the woods.
In the midst of a green meadow where primroses bloomed, I saw the Empress seated on a throne covered with ivy and lilacs. A green wreath adorned her golden hair and, above her head, shone twelve stars. Behind her rose two snowy wings and in her hands she held a sceptre. All around, beneath the sweet smile of the Empress, flowers and buds opened their dewy, green leaves. Her whole dress was covered with them as though each newly opened flower were reflected in it or had engraved itself thereon and thus become part of her garment.
The sign of Venus, the goddess of love, was chiselled on her marble throne.
"Queen of life," I said, "why is it so bright and joyful all about you? Do you not know of the grey, weary autumn, of the cold, white winter? Do you not know of death and graveyards with black graves, damp and cold? How can you smile so joyfully on the opening flowers, when everything is destined to death, even that which has not yet been born?"
For answer the Empress looked on me still smiling and, under the influence of that smile, I suddenly felt a flower of some clear understanding open in my heart.
