Officials of the Swedish Academy on Monday said that they have given up trying to contact Bob Dylan for him to acknowledge his Nobel Prize for Literature. Permanent secretary of the academy Sara Danius told a radio channel, "I have called and sent emails to his closest collaborator and received very friendly replies. For now, that is certainly enough.”

Dylan on Thursday became the first musician to win the Nobel Prize for Literature, but the 75-year-old icon is yet to respond to the accolade. Although Dylan has performed in Las Vegas and Coachella after winning the award, he has not acknowledged it.

The academy will present the award at a ceremony in Stockholm on December 10. Danius said they are not sure if Dylan will show up, but added that the "honour belongs to him". However, the permanent secretary added, "I am not at all worried. I think he will show up."

This is not the first time that Dylan has acted in this manner, reported The Telegraph. In 1963, he won the Tom Paine award for civil rights and delivered an acceptance speech for which he had to apologise later. In 2000, he skipped the Oscar ceremony and later accepted the award via a video. In 2007, he gave the Crown Prince of Spain’s ceremony a miss and in 2010 he did not go to the White House to collect the National Medal for the Arts.
