Diego Collado, Diego Collado's Grammar of the Japanese Language
“ In Japanese there is no imperfect. In its place the perfect is used. The perfect is formed in two ways. The first is by suffixing ta to the root of a verb ; e.g., agueta is the preterit of the verb ague,uru 'to offer.' The second is by suffixing te to the root and to that adding gozari,u or ari,u which is then conjugated in the present or the preterit of the second conjugation; e.g., aguete gozaru or aguete gozatta, or aguete aru or aguete atta 'offered, or had offered.' If the particle fáia [faia] is placed before the verb the expression is strengthened ”
