Of a family devoutly attached to the royal cause, to which it is said they had contributed not less than 200,000 l., Glamorgan's religion, his rank, his Irish connections, the intimate confidence of the king which he was known to possess, all marked out his embassy as one of the utmost importance.
The earl arrived in Dublin about August 1, and, after an interview with Ormond, proceeded to Kilkenny.

On the 28th of that month, preliminary articles were agreed to and signed by the earl on behalf of the king, and by Lords Montgarrett and Muskerry on behalf of the confederates.

It was necessary, it seems, to get the concurrence of the Viceroy to these terms, and accordingly the negotiators on both sides repaired to Dublin.

Here Ormond contrived to detain them ten long weeks in discussions on the articles relating to religion; it was the 12th of November when they returned to Kilkenny, with a much modified treaty.

On the next day, the 13th, the new Papal Nuncio, a prelate who, by his rank, his eloquence, and his imprudence, was destined to exercise a powerful influence on the Catholic councils, made his public entry into that city.
This personage was John Baptist Rinuccini, Archbishop of Fermo in the marches of Ancona, which see he had preferred to the more exalted dignity of Florence.
From Limerick, borne along on his litter, such was the feebleness of his health, he advanced by slow stages to Kilkenny, escorted by a guard of honour, despatched on that duty by the supreme council.
The pomp and splendour of his public entry into the Catholic capital was a striking spectacle.
