There are now on exhibition at the Fogg Art Museum two primitive Italian paintings lent by Mr. A. Kingsley Porter, lecturer of architecture at Yale University. One of the pictures is a figure of St. Michael, by the Byzantine Gothic Guariento of Padua. The form is very similar to the figures of the angels of the Heavenly Host, by the same painter, in the Museum of Padua. The other picture is by a pupil of the Paduan Squarcione, Gregorio Schiavone; it was recently shown in the exhibition of Italian primitives at the Kleinberger galleries, New York. It represents a Madonna and Child, both of which have a distinct charm somewhat unusual with this northern master. The paintings will remain at the Museum for about two months.
