Four years later, Lauder's inventive powers were again exercised in producing one of those plays, or 'moralities', which were so common at that time, to celebrate the marriage of the young Mary, Queen of Scots with Francis, Dauphin of France, at Paris, in July 1558. Although these two plays appear now to be lost, the Council Records and the Lord High Treasurer's Accounts enable us to ascertain the nature of the last performance, in which the chief personages were the Seven Planets, and Cupid. There are numerous payments under the heading of "The expensis maid upone the triumphe and play at the mariage of the Quenis Grace, with the convoy, the ["blank"] day of Julij, anno 1558." Many of these relate to the costumes and arrangements.
