Janetto de Tassis also Tasso, and also known as Johann Daxen, Jenne de Taschen was an Italian postmaster and courier. He came from the noble Italian family of Tasso, who were in the service of the Venetians and the Pope. After the takeover of Tyrol by Holy Roman Emperor Maximilian I in 1490, he entered Maximilian's service to organize postal and courier routes to Italy, France and the Burgundian Netherlands. He served Maximilian from 1490 to 1506 as a master courier before retiring to his possessions in Istria. In 1508, after the Venetians conquered Istria, he sided with them to save his lands. He was confined in Pisino as a deserter upon Maximilian's reconquest of Istria in 1509. In 1515 he made his will in Pisino, and died there a few years later, probably around 1517 or 1518.
