-Cambridge: University Library (Adv. D, 3.22 or Ms. Oo. IV.35): Adolf Occo, Imperatorum Romanorum numismata, Antwerp, Plantin, 1579 – book annotated by Jacob Cools (Colius Ortelianus, 1563-1628), the nephew of Ortelius, giving numbers for his coin collection (1,129 in 1603) as well as for the one of Abraham Ortelius (1,925 coins in 1597).
Poem inscribed on verso of title page:
Codice in Occonis minio commonstrat ubique
- Quos habeat nummos Caesareos Colius.
Sicque suos Graecos nummos distinguit in illud
- De Graecis Colius quod sibi scripsit opus.
At quae consulibus inscripta numismata servet
- Illud in Ursini SIC notat usque libro.
[Colius indicates in red, in all places in the book of Occo, which imperial coins he may have. And similarly Colius marks his Greek coins in that work ‘About the Greeks’ that he has written for himself. And this (SIC) marks everywhere in the book of Orsini the coins which he may have, inscribed by the consuls.]
