[3] Other works by Collado have come down to us; cf. a memorial by him published in 1633 (Laures, Kirishitan Bunko, item 411). Such material is, however, only peripherally related to the study of language.

[5] The Press of the Congregation for the Propagation of the Faith was founded in 1626 when the Congregation was at the height of its activity. Grammars of the major non-European languages published during this period are:
| 1628 | Syrian | Abraham Ecchell |
| 1630 | Ethiopian | V. M. Rearino |
| 1631 | Arabic | Thomas Obicini |
| 1632 | Japanese | Diego Collado |
| 1636 | Coptic | A. Kircher |
| 1637 | Arabic | Germano de Silesia |
| 1642 | Arabic | P. Guadagnoli |
| 1643 | Georgian | F. M. Maggio |
| 1645 | Armenian | Clemente Galano |
| 1647 | Syrian | J. Acurense |
| 1650 | Arabic | Antonio de Aguila |
| 1661 | Persian | Ignazio de Jesu |
[6] Rodriguez' own work is strongly influenced by the format found in Manuel Alvarez (1526-1582), De Institutione Grammatica, Libri III (Lisbon, 1572). So much a part of the training in the Society of Jesus was this work that an edition was printed in 1594 as one of the earliest products of the Mission Press at Amakusa.
[7] The palatal semi-vowel is represented, as in most the Christian materials, by a number of transcriptional devices such as i, e, h, and palatal consonants; e.g., fiacu, agueô, cha, and xô.
[8] See the translation, p. [82], n. 8.
[9] Collado's and Rodriguez' analyses agree in classifying the ni-dan verbs and suru into one conjunction, the yo-dan verbs into a second, and the ha-gyō of the yo-dan into a third.
[10] It should be recalled that the Ars Grammaticae is numbered by the page and the Arte by the leaf.
