Aegidius Gelenius

Aegidius Gelenius (10 June 1595 – 24 August 1656) was one of the most respected Cologne historians of his time. He had also at his disposal some Roman age sources that are not in existence today.

He developed a late hatching system for heraldry but it did not gain popularity. Provided by Wikipedia
