 In the cash books of the Brotherhood of Saint Barbara (Compagnia di Santa Barbara) in Florence an Arrigo fiamingo - without specifying surname or profession - was registered for five years, the last time in 1580.This does not necessarily contradicted by the fact that Hendrick received a commission for frescoes in Rome in 1579 and was also registered in the Brotherhood of the Flemish community there in December of that year.The next year he was admitted to the Accademia di San Luca and remained active in Rome and Umbria for many years.
