The third nave window

This window is situated under the gallery and it is impossible to photograph all of the window in a single photograph which is why the top of the window appears to be missing.
The window shows a pair of lighted candles, a sandglass, and a third object which we are unable to identify but which may be an extinguished oil lamp. All of these signify the transience of human existence –
“And all our yesterdays have lighted fools
The way to dusty death. Out, out, brief candle!
Life’s but a walking shadow …” [Macbeth Act 5, scene 5].
