Quintilian
(circ. 90 ce, Rome), Institutio
Oratoria [10.]3.31-32, gives
the following advice:
It is
best to write on wax (ceris)
owing to the facility which it offers for
erasure, though weak sight may make it desirable to employ parchment (membranarum) by
preference. The latter, however, although of assistance to the eye,
delays the hand and interrupts the stream of thought owing to the
frequency with which the pen has to be supplied with ink (32) But
whichever is employed, blank pages (tabellae)
must be left in which one
is free to
make additions at will.
Scribi
optime ceris, in quibus facillima est
ratio delendi, nisi forte visus infirmior membranarum
potius usum exiget... relinquendae
autem in utrolibet genere contra
erunt vacuae tabellae, in quibus libera
adiciendi sit excursio.
