The Four of Pentacles in The Tarot of Prague features details from three Prague buildings from different eras, but that speak to us across time.
The House at St. Luke (U sv. Lukáše) on Loretánské náměstí was built around 1730 as a Baroque townhouse, with a lot of attention paid to symmetry.
St. Luke is seen above the entry showing a painting of the Madonna and Child to his subjects.
While best-known as an author of a Gospel and patron of physicians, students and butchers, Luke is also associated with artists and by some accounts was a painter of icons. He is thought to have painted the Black Madonna of Częstochowa, now in Poland, and a few others that survive to this day. In the medieval era, painters were sometimes in a Guild of St. Luke.
A house sign above the door shows St. Luke and an icon of the Madonna.
