the fresco are all formed and placed to be in a mathematically accurate spatial construction, in which all of the orthogonals join together at the single "vanishing" point on the painting's horizon. What makes this fresco peculiar for its time is its measurable, mathematically expressed space, which is a quality that was rarely produced in Sienese painting during the first half of the Quattrocento. Without a doubt, Domenico's decision to depict one of his frescos with such measured accuracy must have been influenced by realists of Florentine painting such as Masaccio, Masolino da Panicale and Filippo Lippi. Still, Bruce Cole writes about this fresco as one that stays eccentric and stylistically distant to Domenico's Sienese ancestors and Florentine contemporaries. Cole writes that the fresco is a "peculiar blend of realism and fantasy, of immediacy and distance". Because of this, the overall effect of the picture counteracts its realistic layout. Some of the most minute details in the Education and Betrothal of the Foundlings can be found in the floor tiles, rugs, decorated robes and floor to ceiling moldings. The last fresco Domenico was unable to finish all six frescoes in time. Domenico began to have complications in his relationship with the hospital after he was unable to deliver a completed sixth fresco. In addition to this, the hospital had also commissioned Domenico to produce a Madonna della Misericordia, of which he was also unable to finish. Strehlke presents documents that prove that Domenico was put on probation and his payroll was reduced. Strehlke suggests that a strong reason for Domenico being unable to finish his work was due to illness, of which he shortly died upon falling sick. Final years Di Bartolo's last ever (dated) commission was the fresco of the Coronation of the Virgin in the Cancelleria di Biccherna, for the Palazzo Pubblico of Siena. He began to paint four angel heads, but his work was interrupted by his death in 1445. Soon after, the fresco was completed by another Sienese artist Sano di Pietro.
