17. It is of some interest to note that the Paraclete ray sometimes carries a representation of Baby Jesus: we have 19 examples, in 10 of which the baby carries the cross. This can be huge, as in the Ayuntamiento de Valencia, 1515, by a disciple of Juan de Flandes, where it is several times larger than the baby. The first baby appears in 1310–1315 by the Florentine painter Pacino di Buonaguida.
