It is a noble portal, erected in 1460, apparently from designs by Fra Giocondo, with the lion of St Mark in the attic. The statuary, with Sta Giustina on the summit of the tympanum, was added in 1571 and 1578.

The sensation of sound is produced by rapid fluctuation in the pressure of the atmosphere on the tympanum of the Charac- ear.

Examples of Norman work are frequent in doorways, as in the churches of Allestree and Willington near Repton, while a fine tympanum is preserved in the modern church of Findern.

The tympanic process of the alisphenoid bone of the skull is short, not covering the cavity of the tympanum, nor reaching the paroccipital process.

In the tympanum is a relief of Bacchus (wrongly supposed to be of a female, and called the Bal-Kis, i.e."Honey Girl").
