[1] Diego Collado, O.P., _Niffon no Cotoba no Yô Confesion_, etc. (Rome, 1632). For further bibliographic data cf. Johannes Laures, _Kirishitan Bunko_ (Tokyo, 1957). Cf. also Ōtsuka Mitsunobu, _Koriyaado zangeroku_ (Tokyo, 1967), for a Japanese transliteration and concordance. It should be noted that the material in this work had no direct influence upon the concurrently written grammar. The only example in the _Ars Grammaticae_ which might have been borrowed from the _Confesion_ is on p. 23 where we find _doco de qiqi marasuru mo, sono sata va mósanu_ 'although this is heard everywhere, I have heard nothing of it.' which parallels the _Confesion_, p. 6, l. 18; _docu _[_sic_]_ de qiqi marasuru mo; sono sata ga gozaranu_ 'one hears about this everywhere; but, it doesn't seem to be so.' [2] The bibliographical data on these and other works directly related to the study of Collado's Grammar will be found in the section on bibliography which follows. [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. [4] For a brilliantly written biography see Michael Cooper, S.J., _Rodrigues the Interpreter: An Early Jesuit in Japan and China_ (Tokyo, 1974). [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: _Date_ _Language_ _Grammarian_ 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.
