Medieval Monastic Clothing Part 4: Night Clothes/Pajamas

If you’ve read the previous installments of my medieval monastic clothing series, you know what a monk wore in the daytime as well as the underwear they wore. But what did medieval monks wear to bed? Because the medieval era is a period of about one thousand years or so, it depended on what century he lived in.

In Chapter Twenty-Two of The Rule of Saint Benedict, the text is clear that a monk has to sleep clothed. He is also not allowed to wear a belt to bed or sleep with his knife for safety reasons. (The fact that Saint Benedict went out of his way to include this implies that this was an ongoing issue!) But what exactly did he mean by clothed? Well, in Chapter Fifty-Five it’s implied that a monk needed to wear his tunic and cowl to bed. After all, he is supposed to have two sets in case one is in the wash (or if he’s sleeping in it). But this is all in theory. What about in practice?

The answer varies depending on the century.

In the earlier middle ages, clothes specifically designated for nighttime were not really a thing. Night clothes/pajamas were a later medieval phenomenon. So, when Saint Benedict was writing The Rule in the early sixth century it made sense for monks to sleep in their day clothes. However, for hygiene reasons, a monk would wear his extra set of day clothes, not the clothes he wore that day. Ideally, of course. If his second set of clothes were in the laundry, he would have no choice but to sleep in the clothes he wore that day. Also, by sleeping fully clothed it took less time for a monk to get to the church for night offices.

It should be noted that Saint Benedict wasn’t the only monk writing guidelines for the monastic life. In other monastic Rules, what should be worn to bed was also specified. In these texts, monks were allowed a second tunic for sleep. Depending on the author, the tunic might be made of a heavier cloth or one specifically for night use.

Like other guidelines in The Rule of Saint Benedict, over time monks began to get rather flexible with their sleep attire. This is partially due to the fact monks were starting to sleep in separate cubicles instead of open dorms. Or if they didn’t get their own cell, monks would put curtains around their beds for privacy reasons. With more opportunities for privacy, it wasn’t necessary to protect your modesty by sleeping fully clothed. Eventually, a shirt, drawers, and stockings were considered acceptable. This was not without controversy. For example, King Henry V of England attempted to make monks sleep in their outerwear, but he gave up on trying to enforce these reforms. By the early fifteenth century, it wasn’t considered necessary to wear outer clothes to bed at all.

Then by the late fifteenth century, nightclothes was a thing. A monastic night coat was a circular garment that was (probably) thigh length. Monks were expected to wear it with drawers and hose. At Westminster in the 1490s, there is documented evidence of novices wearing night coats as well. This particular night coat was made of black cotton.

Nightcaps were worn too. They were made of linen. However, in the thirteenth century, they were considered an exceptional item. They were only given to monks who got sweaty at night. The nightcap was used so the monk’s sweat wouldn’t ruin their pillow.

Monks had slippers too. During the thirteenth century, Westminster monks were given a new pair two times a year: October 31st and the day before Palm Sunday. Depending on the date, the slippers would either be for winter or summer.
