C. Afonso dos Santos

Very little confirmed biographical information about this author appears to be available in the sources I found. Public-domain library records and ebook listings identify the name as C. Afonso dos Santos and connect it to the Portuguese work O trophéo.

Project Gutenberg lists O trophéo as a Portuguese poetry title originally published in Lisboa by Typ. da Cooperativa Militar in 1907, with the alternate modern spelling O troféu. The work is presented as poetry rather than prose, and modern catalog pages consistently preserve the abbreviated author form rather than expanding the full name.

Because reliable biographical details are scarce, it is safest to remember this author as an early-20th-century Portuguese-language poet known from this surviving publication, whose writing blends romantic feeling with tragic, war-shadowed imagery.
