Translated excerpts from French

Petrópolis, March 13, 1873. "To Mr. Taschereau, director of the National Library of Paris. I recommend to you Dr. Ramis Galuad, director of the National Library in Rio. I hope you will make him admire all the riches of your library, where you were so kind to me. Your affectionate colleague, D. Pedro d'Alcântara."

Rio, April 23, 1874. "Dear Professor, The memory of my visit to your laboratory at the Collège de France remains very vivid in my mind, and compels me to recommend Dr. Freire to you, who has just qualified for the chair of Organic Chemistry at the Rio de Janeiro School of Medicine through a brilliant competition. He has been sent to study in Europe. I am certain that he will honor the reception of the scholars and the affectionate feelings with which I am, Dom Pedro d'Alcântara."

Paris, June 6, 1877. "Sir, I hope you can be in your laboratory at the Collège de France on the 9th for a few moments of conversation, which so many commitments in Paris have prevented me from having elsewhere with you. I plan to visit your laboratory between 1 and 2 o'clock. Your very affectionate colleague, D. Pedro d'Alcântara."

Rio de Janeiro, April 14, 1880. "Sir, you know my love for science, which is, incidentally, too platonic given my position, and my sincere esteem for those fortunate enough to contribute to scientific progress; that is why I naturally express how eager I am to read your essay on chemical mechanics. Even the wise men compel me to be reserved regarding theories, but the principle of maximum effort will further enrich your mastery of synthesis. I ask you to always remember my interest in your work and always believe in your affectionate regards, Dom Pedro d'Alcântara."

Rio, September 14, 1882. "Sir, I recommend to you once again a Brazilian of scientific merit, Dr. Ferreira dos Santos, associate professor at the Rio de Janeiro School of Medicine. He will be perfecting his chemical studies, and I greatly hope for your assistance in the services he will render to his science in my country. For a long time, I have only seen his name in reports; however, I am certain that you believe in the interest that whatever you wish to communicate to me in your letters would cause me, especially if it could contribute to the progress of the study of chemistry in my country. Fortunately, I notice a little more scientific activity. I ask that you always count on the sincere esteem of your very affectionate, D. Pedro d'Alcântara."

Petrópolis, March 20, 1887. "Sir, As a Brazilian, I appreciate your collaboration in the magazine, which advertises itself as dedicated to all the interests of my country, and I am pleased to provide information related to the physical sciences, in which you know I am involved as much as my position allows. In asking you to recall the fond memories of our colleagues, I take this opportunity to express all the esteem I have for you, your affectionate colleague, Dom Pedro d'Alcântara."

Cannes, January 18, 1888. "Sir, your letter gave me great pleasure, as you should be quite certain, for you know how much I esteem you. I am sure that your recommendations will find the best reception from my son-in-law and my daughter. Always keep me informed about your work, for you know perfectly well the interest your affectionate colleague has in it. D. Pedro d'Alcântara."

A man of good character, science, culture, and progress, Dom Pedro II reigned over Brazil for fifty-eight years. Upon inheriting, in succession from his father in 1831, an Empire on the verge of ruin, he profoundly transformed his country, elevating it to a free, civic, and emerging power on the international stage.

Generally considered, even to this day, as the greatest man in Brazilian history, his behavior aroused the respect and admiration of many European scientists and writers, such as Darwin, Hugo, Pasteur, Bell, and Nietzsche.

"I was born to dedicate myself to culture and science," he wrote in his personal diary in 1862. Fluent in more than ten languages, he was a member of the Royal Society, the Russian and Belgian Academies of Sciences, and the American Geographical Society, and was elected to the French Academy of Sciences in 1975. Wishing to put his knowledge at the service of his country, he actively developed national education, scientific and artistic research.

Important correspondence from Dom Pedro II – in my opinion, one of the most fascinating figures in Brazilian history – is becoming increasingly rare; this is perhaps the last. This collection is particularly interesting because it shows – in the final years of his reign – how much Dom Pedro II loved science, how he strove to promote and advance Brazil with the help of France, the two countries that profoundly marked his life.

It is signed and stamped by Mathias Meyer, a French autograph expert since 2010 and a member of the ILAB (International League of Antiquarian Booksellers).

Who selects and certifies the items sold?

All items are selected and certified by Mathias Meyer, a French specialist in autographs, manuscripts, and historical documents since 2010. Throughout his career, he has studied thousands of pieces related to Brazilian history, sports, science, literature, and arts, and is now a member of ILAB (International League of Antiquarian Booksellers) and founder of Glórias.

You can purchase directly from the Glórias website, 24 hours a day, quickly and securely. If you prefer personalized service or have questions before purchasing, you can also contact us by email at contato@glorias.com.br or by WhatsApp at +55 (31) 98221-5758.

What are the payment methods?

We accept payment via Pix or bank transfer, both with a 3% discount for upfront payment, as well as credit card in up to 3 interest-free installments, offering convenience and security for customers across Brazil.

Can I pay for my purchase in installments?

Yes. You can pay in full via Pix or bank transfer with a 3% discount, or pay in up to 3 interest-free installments by credit card, with immediate shipping after payment confirmation. It is also possible to pay in up to 10 installments via Pix; in this case, shipping will be carried out after the full payment of the purchase.

Can I ask for a discount?

We offer a 3% discount for payments made in full (via Pix or bank transfer) or the option to pay in up to 3 interest-free installments by credit card. Furthermore, the prices of our pieces are carefully determined based on international market supply and demand, the specific characteristics of each item, and sales results of similar pieces. For this reason, we typically do not grant additional discounts. However, if you wish to purchase multiple pieces or make an exceptionally high-value purchase, we would be pleased to consider a special commercial arrangement.

How is delivery made? What will I receive?

Delivery time varies approximately from 1 to 10 business days, depending on the recipient's location. In Brazil, we mainly use SEDEX, and for international shipments, FedEx. The document is placed in an elegant laid paper folder and sent in completely discreet packaging. The digital certificate of authenticity and guarantee is sent by email, in PDF format, for security reasons. Shipping is free throughout Brazil. For international shipments, the shipping cost is a fixed R$ 500.00.

Yes. For online purchases, the Consumer Protection Code guarantees the right of withdrawal within 7 days of receiving the item. If you are not satisfied, simply contact us and we will respond promptly to find the best solution, which may include a full refund after the return and verification of the item.

What warranties come with the items?

All items sold by Glórias have a permanent guarantee against eventual certification errors, provided that such error is subsequently demonstrated and confirmed by Mathias Meyer. In this event, the buyer will be fully reimbursed. To date, this situation has never occurred. The guarantee does not cover natural alterations or damage caused by improper storage, exposure to light, humidity, insects, or any other external factor that may compromise the preservation of the paper or ink.

Can I resell this piece in the future?

Yes. Should you wish to sell your piece in the future, please contact us. We will be happy to guide you and help you find a new collector, either through a direct sale or through a specialized auction organized by Glórias.

How can I add value to my collection?

If your goal is to go beyond an isolated purchase, the ideal is to build a coherent collection around a theme, a personality, or a historical period, such as aviation pioneers, women who made history, love letters, old photographs of Rio de Janeiro, Oscar Niemeyer, Pelé, or Ayrton Senna. Mathias Meyer can guide you in forming a consistent collection, according to your interests, objectives, and budget.

How should I store my document or autograph?

To preserve your document in the best condition, we recommend against laminating it or keeping it permanently framed, as paper needs to breathe and prolonged exposure to light can accelerate its deterioration. Ideally, store it in a dry, dark, and clean place, protected from humidity, extreme temperatures, dust, and insects, ensuring its preservation for many decades.

Why aren't these pieces in museums?

Throughout history, much of the world's documentary heritage has been preserved thanks to private collectors and dealers. These enthusiasts of historical documents play a fundamental role in the discovery, study, and preservation of pieces that can later be loaned, donated, or sold to museums and other institutions. In Brazil, where many museums have limited financial resources and staff, this collaboration is even more important. Glórias maintains relationships with public institutions, museums, and researchers, both in Brazil and abroad, sharing discoveries, knowledge, and, in some cases, documents for exhibitions.

Can I offer you a part to buy?

With pleasure. The first step is to conduct a preliminary assessment, which will determine the level of authenticity, market value, and the best strategy for your piece. Depending on the outcome, there are several possibilities, such as direct sale, consignment, or a specialized auction.

Where do the parts sold by Glórias come from?

Every document has a unique story. Most of the pieces offered by Glórias were inherited from families who contacted us, while others were acquired at auctions, where they were poorly identified or undervalued, or came from antique dealers, collectors, or companies. Behind every rare document there is a singular trajectory, which makes collecting a fascinating way to preserve and transmit history.
