Gregory Thaumaturgus
The side walls supporting the vault over the altar are decorated (towards the front) with four niches containing statues, two on each side: St. Gregory Thaumaturgus (the Wonderworker) and Our Lady of the Conception, and St. Bridget and "Ecce Homo" (or “Our Lord of the Green Staff”). Towards the back along these side walls are four paintings representing St.Stanislaus Kostka, St. Paul Miki, St. John Martyr, and St. Diogo Martyr. The latter three are Jesuit saints martyred at Nagasaki, Japan, in 1597. See Caetano, "Pintura", nos. 112-115 (vol. 1: 117-120). The attributed artist is Domingos da Cunha, the "Cabrinha". The three martyrs are probably St. Paul Miki, St. John Soan de Goto, and St. Diogo (or James) Kisai (or Kizayemon), Jesuit brothers or "temporal coadjutor" in Japan.
