The Elf on the Shelf: A Christmas Tradition is a 2004 children's picture book, written by Carol Aebersold and daughter Chanda Bell and illustrated by Coë Steinwart. The book tells a Christmas-themed story, written in rhyme, that explains how Santa Claus knows who is naughty and who is nice. It describes elves visiting children between Thanksgiving and Christmas Eve, after which they return to the North Pole until the next holiday season. The Elf on the Shelf comes in a keepsake box that features a hardbound picture book and a small soft toy in the form of a pixie scout elf.
Christina (18 December [O.S. 8 December] 1626 – 19 April 1689) reigned as Queen of Sweden from 1632 to 1654.[note 1] She was the only surviving legitimate child of King Gustav II Adolph and his wife Maria Eleonora of Brandenburg. At the age of six, Christina succeeded her father on the throne upon his death at the Battle of Lützen, but began ruling when she reached the age of 18.
Christina is remembered as one of the most educated women of the 1600s. She was fond of books, manuscripts, paintings, and sculptures. With her interest in religion, philosophy, mathematics and alchemy, she attracted many scientists to Stockholm, wanting the city to become the "Athens of the North". She was intelligent, fickle and moody; she rejected what the sexual role of a woman was at the time. She caused a scandal when she decided not to marry and in 1654 when she abdicated her throne and converted to Roman Catholicism. She changed her name from Kristina Augusta Wasa, adopting the name Christina Alexandra.[note 2]
At the age of 28, the "Minerva of the North" moved to Rome. The Pope described Christina as "a queen without a realm, a Christian without faith, and a woman without shame". Notwithstanding all that, she became a leader of the theatrical and musical life and protected many Baroque artists, composers, and musicians.
Being the guest of five consecutive popes, and a symbol of the Counter Reformation, she is one of the few women buried in the Vatican grotto. Her unconventional lifestyle and masculine dressing and behavior have been featured in countless novels, plays, opera and film. In all the biographies on Christina her gender and cultural identity play an important role.
