OR, Dido Twite leaves London
Imagine the scene: it is Christmas Eve, the date for the traditional Mince-pie Ceremony at Battersea Castle. An unfamiliar London custom? It’s not surprising as this is 1833 in the alternate history of Joan Aiken’s Wolves Chronicles, also known as the James III sequence. James III is the Stuart monarch and he has travelled by sled from Hampton Court to be at the ceremony. On the frozen Thames.
If that seems unlikely, consider this: for two centuries we had a Little Ice Age when rivers regularly froze over. So deep and long lasting were these conditions that Frost Fairs were held on the Thames, when it was even possible to light bonfires on the ice without repercussions. The last great frost fair occurred during the winter of 1813 to 1814. A famous print shows people and tents on the ice: to the left is Three Cranes Wharf near Blackfriars in the City, and in the distance we see a bridge with around twenty stone piers; this must be Old London Bridge (Southwark Bridge wasn’t built till 1819) which had had its old houses and shops demolished in the mid 18th century.
But I’m getting ahead of myself. Black Hearts in Battersea begins one “fine warm evening in late summer” with Simon leading his donkey over Southwark Bridge in London. Joan Aiken isn’t more specific than this so I’m guessing this might be at the tail-end of August. Alternatively it may be that late September is the period she means. Why? Here’s my thinking.
