James Joyce and his novel Ulysses are being remembered today.
The annual Bloomsday celebration will see a host of events taking place, including tours, artistic performances and readings.
The majority are online again this year while there are a few in-person across the capital.
As in previous years, President Higgins and Sabina will mark Bloomsday, 16 June, with a celebration of the rich legacy that James Joyce has given, and continues to give, to Ireland and the world.

Pat Liddy runs walking tours and says they won't let the pandemic dampen their spirits.
"Last year we could do very little, but today we're restarting the engine, as it were," he said.
The history enthusiast says Blooms Day is Ireland's "most popular day abroad" - second only to St Patrick's Day.
While he Pat expects fewer people than previous years, he's looking forward to the celebration.
"You'll see people dressed in the glorious costumes from that day in 1904".
Pat Davitt says the day is all about bringing a "little sparkle" to the streets of Dublin and not taking yourself too seriously.
