Oberon’s potion

I suffered – even you will now agree –
A veritable mid-summer night’s dream:
Productive both of roundels and of faery songs.
Remember Oberon’s flowery words to Puck:
‘I know a bank where the wild thyme blows,
Where oxlips and the nodding violet grows’?
Here’s a test of just how literate you are:
Do those two lines flow on through eglantine
To the enchantment of Titania and the rest?
We both know now that Oberon’s secret potion
Played me as an ass for a brief, wild time.
But you? Titania? You’d no such notion.
