Pieter Gillis (28 July 1486 – 6 or 11 November 1533), known by his anglicised name Peter Giles, the gallicized Pierre Gilles and sometimes the Latinised Petrus Ægidius, was a humanist, printer, and secretary to the city of Antwerp in the early sixteenth century.
[3] He seemed to have recommended the painter Hans Holbein the Younger to the court of England, where Thomas More received him delighted.
[3] Thomas More's Utopia, although fictional, includes Pieter Gillis as a character in Book I.
More dedicated Utopia to Gillis, who may have designed the Utopian alphabet.
They first met when diplomatic business brought More and Cuthbert Tunstall to Antwerp.
