Jan Simonides Montanus was a Czech composer of the Renaissance era.
He was born in Kutná Hora, between 1530 and 1540, and died at the same place, in 1587.
He was an Utraquist and a favourite author of the times. His works represent late 16th century Utraquist polyphony.
He was a schoolmaster at St. Barbara’s Church. Today 22 of his works are known, but only one them — the composition "Aurea Luce" — has been preserved whole, in Český Krumlov’s song collection. He composed masses with Latin lyrics, motets, and songs in both Czech and Latin.
