"Fronte Capillatâ," &c

On the Grammar School at Guilsbro, in Northamptonshire, is inscribed the following hexameter:— "Fronte capillatâ post est Occasio calva." I suppose it alludes to some allegorical representation of *Occasio*; and is intended to convey the same meaning as our English proverb, "Seize time by the forelocks." From what author is this inscription taken?
