Mensis Intercalaris, 1612

Here is today's distich by John Owen, with an English translation by Thomas Harvey, 7.42. And yes, the year 1612 was a leap year. Note that Owen is not saying here that there was an intercalary month in 1612; instead, he is explaining why it is that February, alone of all the months, is the one that has an intercalary day added every four years.

Mensis Intercalaris, 1612
Cur quarto solus crescit Februarius anno?
Hic minimus lunae mensis ab orbe fluit.

THE INTER-CALAR MONTH, 1612
Why February sole each fourth year grows?
’Cause ’tis the least month from the Moon that flows.
