[337] _The Memorias da Academia Real das Sciencias de Lisboa_, in which that academy exhibits its labours for the advancement of knowledge, more particularly of the mathematical and physical sciences, are totally distinct from the _Memorias de Litteratura Portugueza_, which have been published by that academy since the year 1792. These last _Memorias_ consist partly of philological and critical treatises on the Portuguese language and literature, and partly investigations relating to the ancient history and constitution of Portugal. The singular union of two departments so essentially distinct, arose out of the French idea of _littérature_, which had been adopted in Portugal. The worthy members of the academy well might, as indeed they intimately did, find it difficult to determine what was to be called literature. To reconcile all opinions, therefore, they included under that title national history. Germans, however, are by no means entitled to make this mistake, a subject of reproach, while they continue to employ the comprehensive word _literature_ to designate merely the knowledge of books.--I have seen as yet only six volumes of the _Memorias de Litteratura Portugueza_. The sixth was published in the year 1796. [338] Barbosa Machado, in his dictionary of learned men, gives a catalogue of the writings of the Count da Ericeyra, including those which remained unprinted up to the year 1747. None of these unprinted works have, it seems, been submitted to the press since that period, though they comprise a whole collection of the minor _Obras Poeticas_ of the author, together with several prose works, on subjects of general utility; as for example, a _Methodo dos Estudos_ (Plan of Study.) [339] _Henriqueida, poema heroico, &c. composto pelo illustrissimo e excellentissimo Conde da Ericeyra D. Francisco Xavier de Menezes, &c._ (including all the titles of the Count), _Lisboa occidental_, 1741, in 4to. The distinction of _Lisboa oriental_ and _Lisboa occidental_ is founded on an ecclesiastical division of the city. [340] See page 246. [341] The poem commences thus:-- Eu canto as Armas, e o Varaõ famoso, Que deo a Portugal principio Regio, Conseguindo por forte, e generoso, Em guerra, e paz o nome mais egregio; E animado de espirito glorioso Castigou dos infieis o sacrilegio Deixando por prudente, e por ousado, Nas virtudes o Imperio eternizado. Europa foy da espada fulminante Teatro illustre, victima gloriosa, Asia vio no seu braço a Cruz brilhante, E ficou do seu nome temerosa: De Africa a gente barbara, e triumfante Selhe postrou rendida, e receosa, Para ser fundador de hum quinto Imperio Que do Mundo domine outro Emisferio. [342] Naõ Calliope heroica agora invoco. Tu me inspira, ó Deidade, &c. [343] The following is part of the picturesque description of Henry’s entrance into the sybil’s cave.
