Johannes a Leydis
Johannes a Leydis or Jan Gerbrandszoon van Leiden was a Dutch chronicler from the 15th century. A Leydis died in 1504. Life. Not much is known with certainty about Johannes a Leydis' life. In all likelihood he came from a family of poorters (a special type of citizenship) from Leiden. He entered the carmelite monastery in Haarlem before 1455. In 1476 he was named prior of the monastery, but in 1479 we find him as prior of the monastery at Woudsend in Friesland. It seems that, during the struggles between the Vetkopers and Schieringers, discipline had become  lax in the monastery. A Leydis attempted to reform the monastery, but apparently encountered so much resistance to his reforms that he was forced to leave in 1480. From sources we know that A Leydis was back in the monastery in Haarlem in 1495, filling the function of subprior. A Leydis died in 1504 in Haarlem. During the Hook and Cod wars, A Leydis supported the Hook faction. His sympathies lay in particular with the family van Brederode and the Egmond Abbey. Historical work. Johannes a Leydis is mostly known as a historian. He wrote the following works: The work  of Johannes a Leydis was well known in the first half of the 16th century, and was used as a source by early humanist historians like Cornelius Aurelius and Reinier Snoy. Later on, the tendency of A Leydis to include fantastic stories in his work was criticised, with the harshest criticism coming from Janus Dousa.
