Cogita Quid Desit Tibi

This poem is from a book published in 1624 by Jean Pignewart (Iohannes Pignevvart), a Cistercian monk and scholar. He attributes his collection of distich poetry to "Cato Bernardinus," invoking both the legendary "Cato" of Latin distich fame and also Saint Bernard of Clairveax who was famously associated with the Cistercian order.
