Background: Hans Holbein the Younger (German: Hans Holbein der Jungere) (c. 1497 - between 7 October and 29 November 1543) was a German artist and printmaker who worked in a Northern Renaissance style. He is best known as one of the greatest portraitists of the 16th century. He also produced religious art, satire and Reformation propaganda, and made a significant contribution to the history of book design.
Context: On 29 August 1528, Holbein bought a house in Basel, in St Johanns-Vorstadt. He presumably returned home to preserve his citizenship, since he had been granted only a two-year leave of absence. Enriched by his success in England, Holbein bought a second house in the city in 1531.  During this period in Basel, he painted The Artist's Family, showing Elsbeth, with the couple's two eldest children, Philipp and Katherina, evoking images of the Virgin and Child with St John the Baptist. Art historian John Rowlands sees this work as "one of the most moving portraits in art, from an artist, too, who always characterized his sitters with a guarded restraint".  Basel had become a turbulent city in Holbein's absence. Reformers, swayed by the ideas of Zwingli, carried out acts of iconoclasm and banned imagery in churches. In April 1529, the free-thinking Erasmus felt obliged to leave his former haven for Freiburg im Breisgau. The iconoclasts probably destroyed some of Holbein's religious artwork, but details are unknown. Evidence for Holbein's religious views is fragmentary and inconclusive. "The religious side of his paintings had always been ambiguous," suggests art historian John North, "and so it remained". According to a register compiled to ensure that all major citizens subscribed to the new doctrines: "Master Hans Holbein, the painter, says that we must be better informed about the [holy] table before approaching it". In 1530, the authorities called Holbein to account for failing to attend the reformed communion. Shortly afterwards, however, he was listed among those "who have no serious objections and wish to go along with other Christians".  Holbein evidently retained favour under the new order. The reformist council paid him a retaining fee of 50 florins and commissioned him to resume work on the Council Chamber frescoes. They now chose themes from the Old Testament instead of the previous stories from classical history and allegory. Holbein's frescoes of Rehoboam and of the meeting between Saul and Samuel were more simply designed than their predecessors. Holbein worked for traditional clients at the same time. His old patron Jakob Meyer paid him to add figures and details to the family altarpiece he had painted in 1526. Holbein's last commission in this period was the decoration of two clock faces on the city gate in 1531. The reduced levels of patronage in Basel may have prompted his decision to return to England early in 1532.
