Mediaeval Baebes Aria lyrics

I have wist, sin I couthe meen
That children hath by candle light
I have wist, sin I couthe meen

That children hath by candle light
Her shadewe on the wal iseen
And ronne therafter all the night

Bisy aboute they han they han ben
And whom they catchen it best wolde wene

I have wist, sin I couthe meen
That children hath by candle light
The shadewe catchen they ne might

For no lines that they couthe lay
This shadewe I may likne aright

To this world and yesterday

Bisy aboute they han they han ben
And whom they catchen it best wolde wene

I have wist, sin I couthe meen
That children hath by candle light
Her shadewe on the wal iseen
And ronne therafter all the night.

Bisy aboute they han they han ben
And whom they catchen it best wolde wene
Bisy aboute they han they han ben
And whom they catchen it best wolde wene
