Their father, Guillaume de Dinteville, was lord of Chenets, Polisy and Dompmartin, bailli of Troyes and écuyer to Duke François, son of François I. A prominent figure of the kingdom, he belonged to an influential family: his brother François II de Dinteville (1498–1554) was a canon of Auxerre, chaplain to Louise of Savoy, Bishop of Riez and ambassador to Rome; another brother, Jean II de Dinteville (1504–1555), was a royal counsellor and ambassador to the court of England, where he was portrayed by Hans Holbein the Younger in the famous painting now held at the National Gallery, London.
The motto IN TE SPERAVI NON CONFVNDAR is drawn from verse 2 of Psalm 31 (Vulgate), originally addressed to God: In te, Domine, speravi, non confundar in aeternum (“In thee, O Lord, do I put my trust; let me never be ashamed.”). In the context of this cup, however, and in the absence of the word Domine, it seems instead to refer to marital union and may be understood as expressing trust placed between spouses.
