Thank you for visiting this website, and for your interest in the first circumnavigation. I hope you liked it, or found it useful.


My name is Tomás Mazón Serrano, and I am the author behind these texts. It took me months of hard work, undertaken during my spare time from my actual job, which has nothing to do with the website -I'm an engineer in a construction company-.

The main premise of the webpage and of the map of the journey is to be loyal to reality- or the documented reality, to be more precise. It is a matter of respect, both to those we refer to, and to those of you that are reading it. Although this expedition caused admiration since the beginning, and therefore much has been written about it, I tried to document it only from original sources, trying to prevent my vision of what happened and how it happened from being distorted. It is based solely on the written documents left by the main characters and their co-protagonists, which are many, fortunately.

The narration of a historic event from a historian must be aseptic, free of prejudice and value judgement. Then, one can make their own idea of what happened and how, with the warranty that they are doing so based on a solid base of documented facts. That is the main purpose.

Once this base is acquired, I invite you to put yourself in the shoes of the people that lived the events narrated in this webpage, and to freely imagine the emotions and feelings our sailors must have felt. The joy of discovering the Strait of Magellan, the despair of seeing their colleagues die, without knowing if they would be next, the excitement of arriving and the glory of being the first to circumnavigate the world. These feelings are probably as real as the documented facts, but it is your job to appreciate the details hidden among the lines to have a richer and more complete image of what happened.

I recognise how hard it is to be completely objective when one talks about this journey. Although I try to stick to the documented facts, I cannot, and I do not want to, hide how much I admire those men, an admiration that has grown the more I have read about them and what they did.

I am passionate about all that is related to the epic expedition that first circumnavigated the world, and I would appreciate any comments, corrections or petitions you wish to do through my email. I invite you to participate in the social media profiles, in which we continue to disseminate the journey of these men.

From June 2019, an English version of this site is available. This has been possible thanks to Eduardo Castillo, one of the readers of the webpage, who emailed me to offer, in an altruistic manner, the translation of all of the texts. Eduardo, to whom I am very grateful for his generosity, he is an enthusiastic in Spanish naval history. He is also an engineer, and lives in Jakarta (Indonesia).

Supporting Eduardo with the texts in English, Clara Panella has provided an excellent contribution translating and editing the texts from the Spanish version.

Lastly, I want to thank all of you who made the investigation and dissemination of this trip a continuous source of satisfaction.
