The writing on the frame reads as follows:
"There's rosemary, that's for remembrance; pray,
love, remember: and there is pansies. that's for thoughts.
There's fennel for you, and columbines: there's rue
for you; and here's some for me: we may call it
herb-grace o' Sundays: O you must wear your rue with
a difference. There's a daisy: I would give you
some violets, but they withered all when my father
died: they say he made a good end,-- "
From Act IV, Scene V of William Shakespeare's Hamlet
