Question: What Filipino playright wrote a zarzuela about the archipelago that Ferdinand Magellan claimed for the king of Spain on Easter Sunday, 32 March, 1521?

<P0-S0> Although the archipelago may have been visited before by the Portuguese (who conquered Malacca City in 1511 and reached Maluku Islands in 1512 ), the earliest documented European expedition to the Philippines was that led by Ferdinand Magellan, in the service of the king of Spain. <P0-S1>  The expedition first sighted the mountains of Samar at dawn on the 16th March 1521, making landfall the following day at the small, uninhabited island of Homonhon at the mouth of the Leyte Gulf. <P0-S2>  On Easter Sunday, 31 March 1521, at Limasawa Island, Southern Leyte, as is stated in Pigafetta's Primo Viaggio Intorno El Mondo (First Voyage Around the World), Magellan solemnly planted a cross on the summit of a hill overlooking the sea and claimed for the king of Spain possession of the islands he had seen, naming them "Archipelago of Saint Lazarus". <SEP> <P1-S0> Walang Sugat (literally, "no wound" or "unwounded") is an 1898 Tagalog-language zarzuela (a Spanish lyric-dramatic genre that includes music, singing, and poetry) written by Filipino playwright Severino Reyes. <P1-S1>  The music for the original version of the play was written by Filipino composer Fulgencio Tolentino. <P1-S2>  "Walang Sugat" was written when the zarzuela became a "potent means" of expressing Filipino nationalism during the Spanish Occupation of the Philippines that followed three centuries of Spanish rule. <SEP> <P2-S0> Enrique of Malacca (Spanish: "Enrique de Malaca" ; Portuguese: "Henrique de Malaca" ), was a native of the Malay Archipelago who became a slave of the Portuguese explorer Ferdinand Magellan in the 16th century. <P2-S1>  Italian historian Antonio Pigafetta, who wrote the most comprehensive account of Magellan's voyage, named him "Henrique" (which was Hispanicised as "Enrique" in official Spanish documents). <P2-S2>  Pigafetta explicitly states that "Henrique" was a native of Sumatra. <P2-S3>  According to biographer-philosopher Stefan Zweig, he is the first person to circumnavigate the world. <P2-S4>  His name appears as "Henrique", which is Portuguese, and is probably the name given to him at his christening, as he was baptised a Roman Catholic by his Portuguese captors. <P2-S5>  His name appears only in Pigafetta's account, in Magellan's Last Will, and in official documents at the "Casa de Contratación de las Indias" of the Magellan expedition to the Philippines. <SEP> <P3-S0> Lapu-Lapu (Baybayin: "ᜎᜉᜓᜎᜉᜓ", Abecedario: "Lápú-Lápú") (fl. <P3-S1>  1521) was a ruler of Mactan in Visayas. <P3-S2>  Modern Filipino society regards him as the first Filipino hero because he was the first native to resist Spanish colonization. <P3-S3>  He is best known for the Battle of Mactan that happened at dawn on April 27, 1521, where he and his soldiers defeated Ferdinand Magellan. <P3-S4>  The battle ended up in the killing of Magellan and the end of his expedition and it delayed the Spanish occupation of the islands by over forty years until the expedition of Miguel López de Legazpi in 1564. <P3-S5>  Monuments to Lapu-Lapu have been built in Manila and Cebu while the Philippine National Police and the Bureau of Fire Protection use his image.
