Beautiful songs from 14th century

Hello steemians,

yesterday I listened old music of 14th century and I found great piece by François Andrieu. Nothing is known about him except that he was born in 1345 and he died in 1400 and except he wrote this elegy on the death of Guillaume de Machaut, (the most known composer of 14th century died in 1377), a four-voice ballade Armes amours / O flour des flours, which is contained in the Chantilly Codex. He also may be tentatively identified as the Magister Franciscus, composer of two other ballades from approximately the same time, though the link can only be made by stylistic similarities.

Let me share this music with you:
