Portable Cross; obverse: Crucified Christ with Virgin, Saints John the Evangelist and Francis; reverse: Crucified Christ with Saints Michael, Paul, Peter, and Louis of Toulouse

Luca di Tommè's Portable Cross with the Crucified Christ, Virgin, and Saint John belongs to this Sienese master's production of liturgical objects combining sculptural and painted elements. The portable processional cross, carried in liturgical processions or placed on altars, typically showed the Crucifixion on the obverse with related devotional subjects on the reverse, creating a complete Passion meditation object that served both ceremonial and private devotional functions. Di Tommè's painting on the cross surface demonstrates the technical versatility expected of a Sienese painter who served both the institutional church's liturgical requirements and private devotional needs.

This work demonstrates Gothic painting techniques.
