Guanahani

Upon his return to Spain in the spring of 1493, Columbus wrote a letter to Luis de Santangel, one of his patrons at the Royal Court of Castile. The letter was printed widely and translated into many languages, spreading the news of the discovery throughout Europe. In the letter, Columbus mentions Guanahani as the name of the first island he discovered, but provides no other details. Nevertheless, this single mention in a widely printed letter would have been enough to make the name Guanahani widely known at an early date.

Juan de la Cosa was the owner and master of the Santa María and as such sailed with Columbus on the first voyage. He was also a cartographer, and in 1500 de la Cosa drew a map of the world which is widely known as the earliest European map showing the New World. The Caribbean portion of the map shows Cuba and Hispaniola clearly, and a much more confused rendering of the Bahamas. Nevertheless, Guanahani is drawn in the Bahamas in a form that appears to show a group of islets rather than a single island, lying due north of the Windward Passage between Cuba and Haiti, in the central part of the Bahamas islands chain.

Columbus' so-called log, more properly referred to as the Diario, is an abstraction made by Bartolomé de las Casas, a Spanish monk and friend of the Columbus family, probably sometime in the 1540s.

When Columbus returned to Spain after his first voyage, he reported to the royal court at Barcelona and presented his original log to the Spanish sovereigns. Queen Isabella ordered that the log be copied. The original soon disappeared, but the so-called 'Barcelona copy' was returned to Columbus prior to his second voyage and was in his possession at the time of his death in 1506. It then passed to his son Fernando and remained in his vast library for many years. At some point, Las Casas got his hands on the Barcelona copy and made the abstraction we today call the Diario. Although most of the Diario is written in the third-person of Las Casas, nearly all of that portion dealing with Columbus' movements in the Bahamas is in the first person of Columbus himself, and is (according to Las Casas) a direct quote from the Barcelona copy.

The Barcelona copy disappeared late in the 16th century, but Las Casas' Diario was discovered intact in 1795 by Ferdinand de Navarette and published 30 years later. The Diario remains the most authoritative and detailed account of Columbus' movements and activities on the first voyage.

In 1571, a biography of Christopher Columbus, written in Italian, was published in Venice. The book was a translation of a Spanish manuscript written by Columbus' second son, Fernando Colón, between 1537 and 1539. The Spanish manuscript eventually was translated into Italian and published by Alfonso Ulloa, a Spaniard making his living in Venice as a professional translator.

It is clear from the context that Fernando must have been working from the Barcelona copy when he wrote the portion of the biography describing the first voyage, as many details in the biography agree precisely with the Diario. In that sense, the primary utility of the biography is as a validity check on the Diario, a test which vindicates Las Casas in many respects. However, there are a few descriptions in the biography that are not already in the Diario. Most importantly, the biography asserts that Guanahani was fifteen leagues (45 miles) long, which seems contrary to Columbus' implication in the Diario that he had seen the entire island on a single day's boat trip.

One question in dispute is whether Guanahani was one island or more than one. Evidence is said to be inconclusive. Columbus never says specifically that Guanahani consisted of more than one island, something which is surely worth noting. But he does say that Guanahani had "another part, which is the eastern part"; and to explore that eastern part, he used a boat rather than walking, which may be significant. On reproductions of the map by Juan de la Cosa, who was with Columbus, Guanahani looks to some researchers like a string of small islands.

At 10 p.m. on 11 October Columbus saw a light "like a small wax candle that rose and lifted up".[10] He pointed it out to other people on board, some of whom were able to see the light, while others did not. The actual landfall was about 35 miles from the location Columbus saw the light, so if taken that the light was from a ground-based source, then it could not have been from Guanahani, but must have been from another island farther east. For the Plana Cays theory, the light would have been on Mayaguana. For Conception, it could have been on Cat Island, Watlings Island, or Rum Cay. For Caicos, it could have been on Grand Turk. For Cat Island, it could have been on Watlings Island, and for Lignum Vitae Cay it could have been Eleuthera Island. The Watling's, Grand Turk, and Egg Island theories have no ready explanation.

Leaving Guanahani late on 14 October, Columbus said "I saw so many islands I did not know how to decide which one I would go to first".[11] Aiming for the largest, he estimated its distance by eye at five leagues, while other islands were both nearer and farther than that.

He arrived at Island II around noon, delayed by a contrary marea (usually translated as "tide", although "breeze" is possible), re-estimating the distance as seven leagues rather than five. Island II had a coastline facing Guanahani that ran north–south for five leagues, and another coastline ("which I followed", says Columbus) that ran east–west for more than ten leagues.

At this point comes a contentious passage in the log: "And since from this island I saw another larger one to the west, I spread sail to go forward all that day until night, because [otherwise] I would not have been able to reach the western cape of the island".[12] From this it is unclear whether the "western cape" at which Columbus anchored that night was on the island with the five- and ten-league coastlines, or the larger island to the west; in other words, it is unclear whether Columbus was adjacent to one or two islands on 15 October. Those who prefer the two-island interpretation call these Island IIa and Island IIb.

The log gives two descriptions of the sail from Island II to Island III on 16 October: in the first version, Columbus leaves at 10 AM and sails nine leagues east–west to reach Island III;[13] in the second version, Columbus leaves at noon and sails eight leagues "almost east-west" to reach Island III.[14]

Columbus also gives somewhat contradictory information on the size of Island III, saying at first (before actually exploring the island) that it "may well be" more than 28 leagues long;[15] but later saying only that "I saw quite 20 leagues of it but it did not end there."[16]

But Columbus does give quite detailed information on the coastline of Island III, more so than any other island he visited. On the evening of 16 October, he arrived at a cape where the coastlines ran NNW and SSW[17] (though some scholars see a possible transcription error here). The following morning (17 October) he followed the coast NNW, and when he was two leagues distant from the end (or "the cape") of the island, he found a "wonderful harbor" with a small island in its mouth forming two narrow entrances. Going into the harbor with boats, he found it too shallow for use and put the boats ashore for water instead. Leaving the harbor after two hours, he then sailed northwest (rather than the previous NNW) "so far that I viewed all that part of the island as far as the coast that runs east-west".[18]

Thus there are four coastlines described at Island III: from the arrival cape, one coast runs SSW, one runs NNW; following the second coast NNW, Columbus arrived at a harbor; continuing along that coast, the coastline runs NW, and then W. These four coastlines and harbor are an essentially perfect fit with the southern part of Long Island.

Columbus ran into foul weather on the night of 17-18 October and gained sea room to avoid running onto a lee shore. He returned to Island III on the 18th, but the log does not specify where on the island he anchored that night. The following morning, 19 October, he split his fleet to search for the island of Samoete that his kidnapped native guides had told him about.

Leaving his Island III anchorage at dawn, Columbus sent Niña SSE and Santa María SE, while Pinta was sent "east and southeast" (contrary to the ESE mentioned in some sources). Thus the ships were able to sweep a large area of ocean in search of the island whose position was only vaguely known. The Santa María herself raised the island before 9 AM, and signalling the other ships to rejoin, Columbus reached Island IV before noon, arriving at the northern point.[19] Columbus describes this point as being surrounded by a reef, with a small island nearby.

Columbus's descriptions of Island IV are, at best, confusing. He describes Island IV being "on an east-west course" from Island III (which contradicts his previous description of the fleet's movements in the search), and he also asserts that from the northern point the coast ran west for 12 leagues, to its western cape, Cabo Hermoso.[20] The direction of this coastline running west contradicts both Columbus's own arrival at the island (since he arrived at the north point by sailing east, and did not arrive at Cabo Hermoso first) and his later description of his departure from this northern end of Island IV (as he departed sailing SSW and yet did not run aground).

From Cabo Hermoso, Columbus described a "great bight" to the northeast. Further confusing the issue, Columbus then says that he believes Cabo Hermoso is on a separate island from Samoete.[21] The following morning (20 October), he tried to enter the bight in order to circumnavigate the island. That attempt soon proved futile because it was too shallow, and Columbus reversed course and returned to the northern end, awaiting the arrival of the King which his kidnapped native guides had told him about.

After two days of fruitless waiting for the King and another day becalmed, Columbus departed from the northern end of Island IV at midnight on 24 October, setting his sights on Cuba, the large island to the south he had been told about. He sailed WSW until dawn on the 24th, then was becalmed again until noon, making scant progress in the afternoon. At some point, he fixed his position at seven leagues southeast of Cape Verde, which he describes as being "in the western part of the southern part" of Island III.[22] From that point, he made two leagues on a doubtful course under a rising wind; then, the morning of 25 October, he made five leagues WSW and another 11 leagues west when they sighted the Ragged Islands, which he called the Islas de Arena ("Sand Islands") running north–south at a distance of five leagues.[23]
