BARLÆUS, or BAERLE, Gaspar, professor of philosophy at Amsterdam, and one of the best Latin poets of the seventeenth century, was born in 1584. There was scarcely any event of importance while he lived that was not celebrated by him, when reasons of state opposed no obstacle to it. He was a great defender of Arminius, and showed his abilities in history by his relation of what passed in Brazil during the government of Count Maurice of Nassau, published in 1647. He died in 1648.
