These ivory tablets usually contain a set of short prayers, and they are frequently illustrated with painted miniatures of sacred subjects exactly like those in the vellum manuscripts of the same date.

Tablet with eight leaves.

Tablet with eight leaves.The South Kensington Museum possesses a very beautiful example of these ivory books; it is of Northern French workmanship dating from about the middle of the fourteenth century. It consists of eight leaves of ivory, measuring 4⅛ inches by 2⅜ inches in width. The six inner pages are extremely thin, no thicker than stout paper, and have paintings on both sides, the two covers are of thicker substance, about a quarter of an inch, and are decorated on the outside with beautiful carved reliefs.

This remarkable work of art has on the inner leaves fourteen very delicately executed miniatures of sacred subjects, single figures of Saints and scenes from Christ's Passion, painted in gold and colours in the finest style of French fourteenth century art, evidently executed by some very skilful illuminator.

Ivory diptychs.

Ivory diptychs.Tablets like this with as many as eight ivory leaves are rare, but a very large number of beautiful ivory diptychs still exist, with carved reliefs on the outside of very graceful style and delicate execution. Most of these diptychs date from the fourteenth century, and are of French workmanship, but they were also produced in England at the same time and of quite equal merit in design and execution.

Inscribed lead tablet.

Inscribed lead tablet.Manuscripts on lead plates, like those of the ancient Greeks, were occasionally used in mediaeval times.

A single lead leaf of an Anglo-Saxon manuscript from Lord Londesborough's collection is illustrated in Archaeologia, Vol. XXXIV, Plate 36, page 438. This leaf measures 6½ inches by 5 inches in width. On it is incised with a stilus in fine bold semi-uncial writing the beginning of Aelfric's preface to his first collection of Homilies, which in modern English runs thus:—"I, Aelfric, monk and mass-priest, was sent in King Aethelred's time from Aelfeage the Bishop, the successor of Aethelwold, to a certain minster which is called Cernel, &c." At the top of the page there is a heading in large Runic characters. Aelfric was sent by Aelfeage Bishop of Winchester to be Abbot of Cerne in 988 or 989, and this interesting page appears to be of contemporary date. It was found by a labourer while digging in the precincts of the Abbey of Bury St Edmunds. Along one edge of the leaden page there are three holes to receive the loops which hinged the plates together, but the other leaves were not found.
