The Lovers looks easy to read at first. Two people, an angel, a bright sky. Call it a love card and move on. The 1909 Rider-Waite-Smith image has more going on: Adam and Eve stand in a garden, a serpent coils in the fruit tree behind Eve, and a mountain sits between them. The scene is exposed. Nothing in it feels private or casual.
That gives the card its pressure. Affection is present, yet so is knowledge of what a choice costs. A relationship may be asking for a promise. A job may be asking for a compromise. Sometimes the choice is smaller, such as saying what you mean instead of keeping a comfortable silence.
Other decks draw The Lovers very differently. Read the image in front of you before importing every detail from the Rider-Waite-Smith card.
