[Illustration: Ring Device of Lorenzo de’ Medici.] Lorenzo de’ Medici had a ring with a diamond; a plume of three colours, green, white, and red, to signify that in loving God he displayed three virtues: the white plume representing faith; the green, hope; the red, charity. Pope Leo X. adopted this device. Pietro de’ Medici had a falcon holding a diamond-ring in its claws, signifying that everything should be done to please God. [Illustration: Ring Device of Pietro de’ Medici.] In the Staunton collection of antiquities (Longbridge House, near Warwick) is a remarkable ring, which is described (with illustrations) in the ‘Archæological Journal’ (vol. iv. p. 358). It is a beautiful gold signet-ring, found, about the year 1825, in the ruins of Kenilworth Castle, by a person named Faulkner, who was in the constant habit of searching among the rubbish with the expectation of making some valuable discovery. Its weight is 4 dwts. 10 grs. The impress is very singular; under a crown appear the numerals 87, of the forms usually designated as Arabic, of which no example has been noticed in this country, except in MSS. prior to the fifteenth century. Above the crown are the letters =s= and =h=; lower down on one side is seen the letter =a=, and on the other =m=. Various interpretations of this remarkable device have been suggested: it has been supposed that it might have reference to the coronation of Elizabeth, Queen of Henry VII., solemnised at Westminster, A.D. 1487, or have been connected with the enterprise of Lambert Simnel, which occurred during that year at the instigation of Margaret, Duchess of Burgundy. Mr. Hawkins considers its age to have been about the reign of Edward IV., the crown with fleur-de-lys ornaments, and the form of the =m= being of similar character to those on his coins; a similar type of crown may, however, be found in earlier times, as shown by the great seals and other authorities as early even as the reign of Richard II. The letters have been supposed to be the initials of a sentence such as ‘Sancta virgo adjuva me’ (the second letter being read as =h=) or, supposing the ring to be referred to the times of Henry VII., ‘Sigillum,’ or ‘secretum, Henrici, anno (14) 87. M{h}.’ The most probable explanation, however, appears to have been proposed by Mr. John Gough Nichols: that the ring, which is of a size suited to a lady’s finger, might have been a betrothal or wedding present; the initials =s.h.= and =a.m.= being those of the two parties, the Arabic numerals indicating the date 1487, and the crown being merely ornamental, frequently used during the fifteenth century on seals by persons not entitled by rank to use them.
