This study explores the manuscript transmission of three anonymous 15
th
century
treatises, with the incipit “Memoria fecunda”, “Nota hanc figuram” and
“Alphabetum Trinitatis”, and their textual relationship to each other. Arguably, both
the
Nota hanc figuram
and the
Alphabetum Trinitatis
are derived from an idea
expounded in the art of memory called
Memoria fecunda
. The interrelation of these
texts clearly shows the close connections between the art of memory and the
meditative literature in the 15
th
century
