In the original version of this article there has been a translation error. The term ‘ribbed’ has been corrected to ‘sail’.

In the sentence beginning ‘Locally, spherical vaults...’ it should have read ‘Locally, spherical vaults had already been introduced and built above the side chapels of the Conventual Church of St John, between 1574 and 1578 (Guido and Mantella 2008); these were subdived by a circular band in relief running at a tangent to the perimetral arches, by a second smaller upper circle closer to the keystone, and by eight radial ribs connecting the two circles.’. The original article has been corrected.
