Eilhard, was professor of poetry in the university of Rostock in 1595; and ten years afterwards was promoted to the professorship of divinity. He wrote notes on Anacreon, Juvenal, Persins, &c., and several other works; but that which made the most noise is a treatise on the nature and origin of evil, entitled Phosphorus de Causa prima et Natura Mali, printed at Rostock in 1596; in which we have a curious hypothesis to account for the origin of moral evil. He supposed two co-eternal principles, not matter and vacuum, as Epicurus did; but God, and Nihilum or Nothing. This being published against by Graver, was defended by Lubin; but after all he is deemed better acquainted with polite literature than with divinity. He died in 1621.
