Pieter de Bailliu
Pieter de Bailliu (1613 – after 1660) was a Flemish engraver.
He was born at Antwerp in 1613. After having learned the first principles of engraving in his own country, he visited Italy for improvement, and there engraved some plates. He returned to Antwerp after 1637, and from 1640 to 1660 engraved several of the works of the most celebrated of the Flemish masters, particularly Rubens and Van Dyck.
According to the RKD he worked in Rome and was the father of the engravers Peeter-Frans and Bernard.
Although by no means equal to Vorsterman, Bolswert, or Pontius, his prints are held in considerable estimation. Meyer's 'Künstler-Lexikon' gives a list of 103 of his engravings, on which his name is found spelled in a variety of ways. The following are his principal works: 
- Lodovico Pereira de Castro, Envoy at the Peace of Münster.
- Claude de Chabot, Envoy to Münster.
- Johann Leuber, Envoy to Münster.
- Pope Urban VIII.
