Not till 1863 was the inventory of 1566, discovered in 1854, published for the Bannatyne Club by Dr.
Joseph Robertson.
Turning to the inventory we read of a valuable present made by David Rizzio to Mary, a tortoise of rubies, which she kept till her death, for it appears in a list made after her execution at Fotheringay.

The murdered David Rizzio left a brother Joseph.

Him the queen made her secretary, and in her will of 1566 mentions him thus:-- "A Josef, pour porter a celui qui je luy ay dit, une emeraude emaille de blanc.
"A Josef, pour porter a celui qui je luy ai dit, dont il ranvoir quittance.
"Une bague garnye de vingt cinq diamens tant grands que petis." Now the diamond cross seen by the young officer in 1845 was set with diamonds great and small, and was, in his opinion, a gift from or through Rizzio.

"The queen wore it out of sight." Here in the inventory we have a bague (which may be a cross) of diamonds small and great, connected with a secret only known to Rizzio's brother and to the queen.

It is "to be carried to one whose name the queen has spoken in her new secretary's ear" (Joseph's), "but dare not trust herself to write".
