Book of Trades Tarot (Jost Amman 1588): Ober of Books
For the purposes of this divination, the suit of Books corresponds to the suit of Swords, or the playing card suit of Spades. This suit represents the element Air, and the social classes of Nobility and Military. Books are considered a Masculine suit. Books typically represent intellect, reason, mental clarity, and the sciences. They may also represent conflicts surrounding the questioner.
The Knights typically concern teenagers or young adults. They may represent impulsiveness, higher learning, enthusiasm, questing for experience and knowledge, change and opportunity, growth, and confidence, sometimes false confidence.
Opinionated. Hasty. Action-oriented. Communicative.
The Knight of Books is often taken to represent a confident and articulate young man, who may act impetuously. The problem is that this knight, though visionary, is unrealistic. He fights bravely, but foolishly. In some illustrations, he is shown to have forgotten his armour or his helmet in his rush to war.
Reversed Meaning: Scattered thought. Disregard for consequences.
This card can represent a clever liar, secrets, or a sly and deceitful confidence trickster. It may also warn that an intended path would be a terrible mistake, or more precisely, that reconsidering one's actions would be a wise decision.
