GERRY RYAN was a "true Dub", the city's Lord Mayor said today.
As a book of condolences was opened at the Mansion House, Emer Costello told the Herald that Dublin "is very much in mourning".
She expects thousands of people to queue outside her residence between this afternoon and Wednesday.
"He was the soul of the nation in many ways," Ms Costello said today, adding: "He was absolutely superb."
She said that while the whole country is mourning the broadcaster, Dublin is particularly upset at his passing.
"He understood Irish people and he understood Dubliners. He was a great Dub."
The Lord Mayor received special permission from the Ryan family to open a book of condolences at the Mansion House and says she hopes to attend his funeral later this week.
"I'd like to clear the diary so that I can represent the city," she said.
Ms Costello added that she saw the shock-jock as a real democrat and a person of compassion.
She recalled meeting him recently at Unicef fundraiser for Haiti. "I think that was a measure of the man," she said.
The book of condolences opened at the Mansion House at midday and will be open tomorrow and Wednesday from 10am-4pm.
