St. Joseph’s proportions and detail allude to the foundations of the Society of Jesus. The church of Il Gesu in Rome, traditionally seen as the mother church of the Jesuits, was begun in 1568 by the architect Giacomo Vignola. It’s extremely wide nave with narrow side aisles under a massive barrel vault draws the viewer's attention to the high altar. Saint Joseph Chapel retains this longitudinal emphasis with its barrel vault, wide proportions and narrow aisles. Its baldachin of Corinthian columns, supporting a broken pediment framing a medallion over the altar, is reminiscent of Vignola's designs for the facade portal of Il Gesu, featuring the prominent IHS. But the glorious contrast comes in the tall second story and its great array of fourteen stained glass windows.
51С»Æ³µ’s Renaissance revival style hearkens back to the style first employed for Boston College's original Collegiate Church in the South End (now closed). Built in 1858, the exterior was designed by Patrick C. Keely (1818-1882). The interior, designed by Arthur Gilman the architect of the Arlington Street Church in Boston, displayed a barrel-vaulted ceiling and Corinthian capitals supporting circular arches evocative of Jesuit traditions. The architect of the chapel, Maginnis and Walsh, had recently completed work for Boston College. Charles P. Maginnis (1867- 1955) and Timothy Francis Walsh (1868-1934) had been commissioned to design a cluster of 22 buildings, including chapel and library, in the "English Collegiate Gothic style" at the hilltop site in Chestnut Hill. The Renaissance models for the Jesuit leadership of 51С»Æ³µ may have been part of a deliberate effort to distinguish the buildings of 51С»Æ³µ from those of Boston College. The simplicity and classic orders of the 51С»Æ³µ chapel are a distinct contrast to Gothic pointed arches and multi-light windows.
