St Dunstan in pictures
London, British Library MS Royal 17 A XVI, f. 9r (detail). Calendar for 17-31 May, with painted pen drawings of (L-R) saints Dunstan (holding his familiar attribute of smith's tongs or pincers), Urbanus, Augustinus and Petronilla. This manuscript is an early 15th century English agricultural almanac, with some text in English as well as Latin; it includes an astronomical calendar with saints' feasts and illustrations of the labours of the months (more on those here), tables for astronomical and liturgical calculations, mnemonic verses and charms. More about this manuscript and the full page image here. The 'labour' for May is hawking - see here for the illustration, on the page facing this one. This is a more workaday manuscript, in style and use, than others we've seen so far.
There's a lot going on in a medieval calendar - this is the second page for May, with dates 17th-31st running across the top line, just under the pictures. The angled lines connect the saints with their feast day. Kathleen Doyle and Cristian Ispir explain some of the common components of calendars on the BritishLibrary's Medieval Manuscripts blog, here.
