His first appearance in Nordic literature is in the saga Karlemagnússaga from the latter part of the 1200s, which in the main consists of passages translated from French texts. His name here is given as Oddgeir danski. This saga was translated into Danish during the 1400s and thereafter Holger Danske became part of Danish folklore with several accounts in the Danish Chronicle first published around 1509.
The Danish national writer Hans Christian Andersen in 1845 wrote the fairytale Holger Danske, where he is described as sitting fast asleep in the casemates of the Castle of Kronborg, with his beard having grown into the table in front of him and his sword in his lap, prepared to wake up to action in case of Denmark being threatened from outside forces. Today his statue can be seen in the casemates of Kronborg as described by Hans Christian Andersen.
