Butuan had been known as the home of the first Catholic Mass in our country. In fact, in 1872 there erected a monument near the Agusan River which celebrates Magellan's arrival and first Catholic Mass in the country on April 8, 1521
He pointed out that scholars like Schumacher, Bernad, and Scott were "uncritical historians" who tried to discredit the "Butuan historiographic tradition" with Robertson's translation as the standpoint.
Pigafetta wrote in his account: "nouve gradi et duo tersi" or nine degrees and two-third (Lat. 9 deg 00 min North) toward the Arctic. The location, as confirmed by the Nancy Manuscript, is the islet of Butuan.
Strong oral tradition, called the Oral Mazaua (Masao) Tradition, which tells that Magellan went to the Islet of Masao, a delta located at the mouth of the Agusan River.
The Map of Mindanao, as presented in Volume 33 of Blair and Robertson's, exhibits the regions of Beaniam, Calagan, Butuan, Maguindanao, and Chipp. Mazaua was not indicated.
Albo's account, in his logbook, as a pilot or "contra-maestre" in one of Magellan's flagship, Trinidad. Based on his careful analysis of Albo and Pigafetta's accounts, Bernad arrived.
The Legazpi Expedition of in 1565 was added as "confirmatory evidence." Accordingly, they were anxious to visit Mazaua, and so they asked for directions from the natives Cabalian. They anchored off Mazaua. But, the natives were hostile so they went to Camiguing, still visible from Mazaua.
Bernad evaluated that: "As pilots of the Legazpi expedition understood it, Mazaua was an island near Leyte and Panaon; Butuan was on the island of Mindanao. The two were entirely different places and in no wise identical."
The geographical situation of Limasawa Island fits Pigafetta's description: the island's tadpole shape running from north to south. Magellan's ships would find themselves to Limasawa if they sailed west or southwest.
Of the pieces of evidence mentioned in the account, one weakened Butuan's claim–Pigafetta never mentioned a river. Butuan is a riverine settlement l situated on the Agusan River. Masao was positioned in the delta of that river.
Hence, with the absence of such geographical characteristics, Butuan's claim is truly hard to justify. Also, it must be pointed out that after the Battle of Mactan, the survivors went to Mindanao, and apparently went to Butuan.
This was vividly narrated by Pigafetta on his account as he stated that they had a trip on a river. However, it traversed the river after Magellan's death.
In August 19, 2020, after decades-long debate, the National Historical Commission of the Philippines sustained its findings that Limasawa in Southern Leyte is the home of the first Catholic Mass in the country.
