Giovanni Armonio Marso (c. 1477 – c. 1553), called Johannes Harmonius Marsus in Latin, was an Italian Renaissance humanist, friar, playwright, poet and organist.
An undated edition was printed at Venice under the title Ioannis Harmonii Marsi comoedia Stephanium urbis venetae genio publice recitata.
In 1502, one of his poems was set to music and sung by Pietro de Fossis [fr] at a reception for Anne of Foix-Candale, then passing through Venice on her way to marry King Vladislaus II of Hungary.
Gabrieli included the text in his account of the event, Libellus hospitalis munificentiae Venetorum in excipienda Anna regina Hungariae.
[1] Some of Armonio's poetry was also included in the second volume of Lodovico Domenichi's Rime diverse di molti eccellentissimi autori, printed at Venice in 1548.
