THE TUNE.
The grand harmony of “Portuguese Hymn” has always been identified with this song of trust.
One opinion of the date of the music writes it “about 1780.” Since the habit of crediting it to John Reading (1677–1764) has been discontinued, it has been in several hymnals ascribed to Marco Portogallo (Mark, the Portuguese), a musician born in Lisbon, 1763, who became a composer of operas in Italy, but was made Chapel-Master to the Portuguese King. In 1807, when Napoleon invaded the Peninsula and dethroned the royal house of Braganza, Old King John VI. fled to Brazil and took Marco with him, where he lived till 1815, but returned and died in Italy, in 1830. Such is the story, and it is all true, only the man's name was 246 / 206 Simao, instead of Marco. Grove's Dictionary appends to Simao's biography the single sentence, “His brother wrote for the church.” That the Brazilian episode may have been connected with this brother's history by a confusion of names, is imaginable, but it is not known that the brother's name was Marco.
On the whole, this account of the authorship of the “Portuguese Hymn”—originally written for the old Christmas church song “Adeste Fideles”—is late and uncertain. Heard (perhaps for the first time) in the Portuguese Chapel, London, it was given the name which still clings to it. If proofs of its Portuguese origin exist, they may yet be found.
“How Firm a Foundation” was the favorite of Deborah Jackson, President Andrew Jackson's beloved wife, and on his death-bed the warrior and statesman called for it. It was the favorite of Gen. Robert E. Lee, and was sung at his funeral. The American love and familiar preference for the remarkable hymn was never more strikingly illustrated than when on Christmas Eve, 1898, a whole corps of the United States army Northern and Southern, encamped on the Quemados hills, near Havana, took up the sacred tune and words—
“Fear not, I am with thee, O be not dismayed.”
Lieut. Col. Curtis Guild (since Governor Guild of Massachusetts) related the story in the Sunday School Times for Dec. 7, 1901, and Dr. Benson quotes it in his book.
