View of the Castle of Zafra, Campillo de Dueñas, Guadalajara, Spain.

St. Joseph's Day

In Valencia, Spain, the feast of the foster-father of Jesus is a week-long festival called Fallas de San Jose (Bonfires of St. Joseph). On St. Joseph's Eve, March 18, fallas—huge floats of intricate scenes made of wood and papier-mâché, satirizing everything from the high cost of living to political personalities—parade through the streets. At midnight on March 19, the celebration ends with the spectacular ceremony known as the crema, when all the fallas are set on fire. The festival is said to reflect the happy and satirical nature of the Valencians. Discuss

Since antiquity, purple garments had been a mark of royalty, as natural purple dyes had to be extracted from mollusks or insects and were thus quite expensive. The lab-created dye made Perkin a wealthy man. In 1906, the chemist was knighted. At the time of his discovery, he had had been trying to create a synthetic version of what? Discuss

Splendid Isolation

Splendid Isolation is the name given to the foreign policy pursued by Britain during the late 19th century, a policy characterized by a reluctance to enter into permanent European alliances or commitments with other powers and by an increase in the importance placed on British colonies, protectorates, and dependencies overseas. Still, there is much debate among historians regarding whether or not the policy was intentional. What marked the end of Britain's so-called Splendid Isolation? Discuss

The young girls in the procession wear big shoulder bows that resemble the wings of a butterfly. They march from house to house, pausing at each door to sing a song and to ask for treats, and the procession always includes a group of angels. Discuss
