A German Orientalist. After intensive studies in Oriental languages, especially and Arabic, he went to Egypt for the first time in 1664-1665 with the intention of going on to , but the patriarch dissuaded him. He then went to Rome, converted to Catholicism, and joined the Dominican order.

Later in Paris, Colbert commissioned him to go to the Orient to buy manuscripts for the . In Egypt for the second time, he resided there from June 1672 to October 1673. He then moved to Istanbul, where he wrote his Histoire de l’église d’Alexandrie (Paris, 1677). He returned to France in 1676 and died in disgrace three years later. He was accused by Colbert of lingering too long in Istanbul and not attempting to reach Ethiopia.

His great skill at discovering manuscripts of great value puts him in the forefront of those who introduced Christian Egypt to the West, while these manuscripts became useful for his own work. , by Abu al-Barakat; of the ; and The and Some Neighbouring Countries were among 355 codices acquired in Egypt that consisted of scalae (comprehensive lexicons of all available and their Arabic equivalents), canonical records, and liturgical books. These manuscripts helped Eusebe Renaudot to write his Historia Patriarcharum Alexandrinorum Jacobitarum (Paris, 1713) and Liturgiarum Orientalium Collectio (Paris, 1716), which remain classic references on the subject to this day.

Two of Vansleb’s publications are of special interest to Coptologists. The Histoire de l’église d’Alexandrie is a brief description of the hierarchical structure of the Alexandrian Coptic church, its customs, , , and canon law. To it, two lists were attached, one about the patriarchs of the church and the other about the “illustrious men of the Coptic nation,” meaning its writers in the Arabic language and their works. This presentation taken from manuscripts listed by Vansleb shows objectivity, scientific approach, and a lack of polemical commentary. The same qualities are found in his Nouvelle Relation en forme de journal d’un voyage fait en Egypte en 1672 et 1673 (Paris, 1677).

Vansleb’s interest in the affairs of the church resulted in works that provide firsthand information on the condition of the , on the of Sitt , of the precarious situation of the patriarch and the bishop of , the number of churches in the province of , and so on. Particularly moving is the account of the pastoral visit of the bishop of to the () on the west bank of the Nile. Vansleb accompanied him and thus came to travel farther south in Egypt than any European up to that time.
