What's really striking about medieval gardens is the way that they appealed to the senses. We expect gardens nowadays to look beautiful and to offer a place of retreat. But, as Landsberg points out, in the Middle Ages, the appeal to the senses was much more carefully constructed. Most of all, these were gardens which smelled amazing. Plants were chosen in order to give wonderful blends of olfactory sensations. Of course, there were many types of medieval gardens - from parklands, to functional vegetable and herb patches, to the soothing dreaminess of cloister gardens.
And colours were used in wonderful ways which went far beyond what looked pretty. The colour green, for example, was seen as a symbol of rebirth and everlasting life: it was also deemed to be particularly calming and refreshing, and the medieval thinker William of Auvergne explained that this was because 'it is half way between black which dilates the eye and white which contracts it' (quoted in Landsberg, p. 36).
It's a shame that medieval gardens have barely survived. Occasionally, we can see the shapes of ancient parklands in the bumpy lay of the land, and there are some wonderful reconstructions and recreations. I have added the recently recreated Queen Eleanor's Garden in Winchester to our list of places to visit this summer... I can't wait!
