I am trying to understand the meaning to the following excerpt from John Keats's Lamia (full poem here), and especially the fourth line below:
Fast by the springs where she to bathe was wont,
And in those meads where sometime she might haunt,
Were strewn rich gifts, unknown to any Muse,
Though Fancy's casket were unlock'd to choose.
I understand "were unlock'd" is the subjunctive but I have a few questions still:
- What does "though" mean here? "As though" or "although"?
- Does casket mean "a small box for jewels" here?
- What does "Fancy's casket" mean here? Why does Keats use a capital letter for "Fancy"?
The meaning of this verse can be understood more or less if "though" means "as though" but I haven't found this meaning in the dictionary. Otherwise, what does the verse mean?
