With the crowd indulging in the Mexican Wave, Ireland looked comfortable but Simon Webster's 52 minute try, converted by Colin Paterson, helped focus Irish attention and Bowe scored the first of his tries after O'Gara's delightful backward flip pass found Andrew Trimble who sent his soon to be ex-Ulster colleague scorching for the tryline, Bowe's outstretched arm earning a well worked score.
Scotland enjoyed the better of the opening exchanges but teak tough forward defence left tem relying on a backline that really didn't have the guile to beat their Irish opposites.
The game's opening score came in 20th minute when, with the Irish backs lined up left on their put-in to a scrum seven metres out, Jamie Heaslip picked and went right then passed inside to Wallace who scored with some degree of ease under the posts.
Paterson knocked over a penalty four minutes later but almost immediately Robert Kearney was the beneficiary of clever play by O'Gara and then skipper Brian O'Driscoll whose long pass sent the Dundalk man over on the left for his first senior international try.
Any hopes of a Scottish revival were knocked firmly on the head with the early second half try from Horan, with Webster's try simply a wake-up call for an Irish side fully deserving of this victory.
