The Voyage of the Hui Corra (Author: Unknown)

section 63

‘What causes that, O man?’ say they.

‘I will tell you,’ quoth he. ‘I stole a horse from a brother of mine, and I rode it on a Sunday, and I am being punished therefor, with a horse of fire between my legs32 continually; and that is the punishment of everyone who rides on a Sunday33.’

They go thence afterwards.
