 Crathorn is less well known than other fourteenth-century atomists such as the Oxford thinkers Henry of Harclay (d. 1317) and Walter Chatton (c. 1285–1344), or the Parisians Gerard of Odo (1290–1349), Nicolas Bonet (d. 1343), and Nicolas of Autrecourt (1299–1369) (Murdoch 1974, 1982; Grellard and Robert 2009), yet we find several questions on the divisibility of the continuum in his Sentences commentary (particularly I Sent., q. 3, but also qq. 4 and 14–16). He affirms that a continuum is divisible into a finite number of atoms that are not mathematical points but its real, physical parts (I Sent., q. 3; for discussion, see Wood 1988, Robert 2009a). Atoms are thus real singular entities with discrete magnitude or quantity and a proper nature. For example, he says that there are atoms of gold and atoms of lead, and that these are different kinds of things (I Sent., q. 14). Crathorn’s atomism is far from that of Democritus.
