We often think of December as the entry to winter and to Christmas. In the middle ages, typically, winter featured much more dramatically than Christmas. The calendar pages in Books of Hours showing the labors of December most often feature an image of hog butchering, a boar roast, or a boar hunt (sometimes they feature an image of St. John boiling in oil, or the baking of bread) as December labors of the month.
This wintery scene is a detail from the December calendar page from the Da Costa Hours (Belgium, Bruges, c. 1515) now in The Morgan Library. (MS M.399, f. 13v). The landscape is snowy, and the people are dressed warmly. In the front, a man is slitting the throat of a boar with a knife, while to his right a woman is catching the blood, “bleeding out” the butchered pig. (Today it’s more common to suspend the the pig head-down; medieval images often show the boar on the ground, or on a low trestle table, or yes, suspended.) Behind the woman catching the blood, another woman stands outside of an inn. The inn has a sign showing a star or perhaps a sun. The windows are lined with three people watching the pig slaughter. In the distance, there’s a man with a team of horses and a wagon. The distant scene looks very cold; there’s some show-through of the art on the reverse of the page.
The boar was an important food source, though largely for the wealthy, especially the domesticated boar. The other popular image for December calendar pages was of the boar hunt. While the head was regarded as a trophy, nothing was wasted, and all was used, from the bristles to the trotters.
