Christa Gardner von Teuffel's studies of Italian altarpieces have
provided fundamental insights concerning the original structure and
setting of some of the canonical monuments of Italian late medieval and
Renaissance painting. Studies of panel type and frame architecture are
combined with an investigation of original sites. Archival discoveries
at Florence and Palermo have led to a new assessment of institutional
patronage and private benefaction, and illuminated the formulation of
altarpiece programmes, such as Perugino's Vallombrosan Assumption and
Raphael's Lo Spasimo. These essays contribute enduringly to our
understanding of contractual obligation, design process and altarpiece
installation, and demonstrate the nexus between ecclesiastical and lay
patrons, artists and congregations. The author's pioneering examination
of Carmelite patronage and subsequent investigation of the
iconographical impact of Benedictine and Franciscan reform movements
have prompted others to re-assess the patronage of religious Orders in
the Quattrocento. The pervasive iconographical influence of the Holy
Land is traced through Sansepolcro, Santa Croce in Gerusalemme at Rome
and as far as the astonishing View of Sinai by El Greco.
