Carlo Ubertino Solaro, Count of Moretta (born 1540) was a diplomat from Piedmont serving Emmanuel Philibert, Duke of Savoy.
[11] An English diplomat in Paris, Nicholas Throckmorton, who had previously had identified Moretta as a nephew and successor of Charles de Solier, comte de Morette, and thought him a good skilled courtier, heard that Elizabeth I had failed to give him the usual diplomatic gift on his first visit, and suggested she send a gold chain.
[12] In 1561, Moretta was sent to announce the news of the pregnancy of the Duchess of Savoy, Margaret of Valois, a daughter of Francis I of France.
De Seure heard that Elizabeth I said to Moretta that she was young and did not need to lean on a husband like an old lady with a walking stick.
He watched courtiers ride in costume at "running at the ring" on the sands of Leith, where he chatted to the English diplomat Thomas Randolph.
[22] Rizzio stayed in Scotland, Moretta returned to Piedmont via London and France, convinced that Mary had determined to marry Carlos, Prince of Asturias.
