On the 54 card Astro Myth Lenormand deck...
I bought my cards from Alidastore.com, ordered them through the website. They are oversize and do come with instructions, but I cannot see any dates to when this system came about.
There used to be a website that listed the 54 cards and the classical Greek myth that is assigned to various cards. It's not like the Mythical Tarot where Jason and the Golden Fleece is the suit of Wands: it's more like bits and pieces of the myth attributed to different cards, such as the Nine of Diamonds, one of the clubs, etc....in other words, certain cards of different suits can be a part of the same mythical allegory.
I haven't gotton to the astrology part yet of the Lenormand, but I saw in the instructions, if a card is on the right or left side of a layout, the reader learns to read one portion of the card.
There is a Dutch book on the system, but no English one, aside from the instructions with the deck.
