13th

This would be a perfect picture to geotag. You have the geographic coordinates right there in the photo!

The location on Google Maps. According to the memorial stone itself, the stone was erected July 20, 1911. As such it seems that it would be pretty safe to assume the photo was taken after that date. Though it may be wrong.

According to the 1910 Census, Bloomington, Indiana, had become the new population center of the USA. Another Bain/LOC photo on this subject shows Prof. Wilbur A. Cogshall of Indiana University at Bloomington, who had pinpointed the location: New York Times story, July 22, 1911: query.nytimes.com/mem/archive-free/pdf?_r=1&res=9A03E...

London Times, Thursday, Aug 18, 1814

The Grand Jubilee was celebrated at Dublin by the procession of the Corporation, Charity-schools, and Lord lieutenant to divine service, at St. Patrick's cathedral; after which there was a good dinner at the Castle; and in the evening the Vice-regal party went to Stephen's Green to see "the grand display of fire-works". The Theatre was opened an hour and a half sooner than usual, and the boxes were "free to the ladies."

Edit: not sure if this is the same dinner. On the 17th, the Bury Advertiser says that Jubilee (the procession to the cathedral etc) is due to take place. So the 17th not the 13th.

Looks like the Bury Advertiser was misleading. The lengthy account of the festivities in The Morning Post, Wednesday, August 17, 1814 confirms that it was the 13th.

His Excellency returned to the Castle, and gave a grand dinner. at half-past six, to the principal Nobility and Gentry of the city and its vicinity.

I also noticed that this was shoehorned into the celebrations:

Some time after the service at St. Patrick's had ended, the LORD LIEUTENANT and his suite, attended by the LORD MAYOR, Sheriffs, and a vast multitude, repaired to Sackville-street, where the ceremony of the laying of the foundation-stone of the new Post-office took place.

Hmmm. Still not sure. The Morning Post article is dates the 13th, and refers to the previous day, and the Wikipedia article on the Post Office says the foundation stone was laid on the 12th.

John Spooner From the Freeman's Journal on Tuesday, 2 August 1814, a notice urging Persons to book early for the Dinner and the Ball, "particularly the Dinner, as the number is limited". It cost £2 5s 6d for the Dinner; the Ball cost £1 5s for Gentlemen and £1 for Ladies; and Entrance to the Green was 3s 4d...

John Spooner I'm starting to think there were a few Jublilee Dinners in Dublin on that Saturday 13th August. However the Lord Mayor attended the one at the Rotunda according to the Freeman's Journal, while the Lord Lieutenant "was not present". As our ticket here is "Under the Patronage and Direction of the Corporation of the City of Dublin, a Dinner at the Rotunda attended by the Lord Mayor of Dublin looks like a better bet?? Meanwhile, up at Stephen's Green (and showing that even 200 years ago, Dublin Corporation were taking stick for "street furniture" decisions:

The Paving Corporation practised a curious piece of economy on Friday night. They took away all the lamps from Stephen's Green, to obviate even the chance of losing one by an unlucky explosion! The entire square was, of course, in utter darkness after eleven o'clock, though thousands of people straggled about until near sun-rise. There were, in consequence, some occasional immersions into the dyke, pocket-pickings, and encounterings of unruly horses and more unruly riders, but we have not heard of any lives lives being lost. Demi-smotherings, wet-clothes, and broken limbs are of course objects of little consideration, but how would the account stand if the lives of any of the King's subjects had been lost. At one side of the book we should have written, with all clerical formality - "lost three lives" - at the other, "saved three lamps!"

Plus and lastly, I found this on the G.P.O. re Foundation Stone, in The new Picture of Dublin: or Stranger's Guide through the Irish Metropolis...:

... This superb edifice is built of mountain granite, except the portico, which is of Portland stone. The expense was something more than £50,000. The first stone of this magnificent edifice was laid by his Excellency Earl Whitworth, on the 12th of August, 1815.

One leg shorter than the other?

Resisting the urge to tag cars (as we are wont to do), but I think there's a VW hatchback (maybe a Jetta or Passat), a Renault 5, and a Micra (or maybe a Fiesta). I can't see the OPW allowing anyone (staff or visitor) to park their hatchbacks out front like that any more. More interesting though is the restoration work on the parapet top right. And the trees. Comparing to the 19th century photo they seem to be the same trees and shrubs. And I suppose why wouldn't they be - after 100 years of care and topiary.

Subpopulus Hibernia 100 years ago the photographer would have had his camera mounted on a tripod complete with spirit level. He would also have a a "rising front" on his camera to avoid the dreaded "converging verticals" we see here. Progress eh?? Bob
