Patnubayan nawa tayong lahat ni Leonard. Paumnahin din sa lahat. Sampung beses kong sinubukang tumanggi ngunit kumbaga sa basketbol, ang score po ay Imelda Sarmiento, 100, at ako po ay zero. Ang consolation prize ko lang ay nandito rin po kayong lahat dahil sa powers niya.

Cycling through the fabled history of an opera house, now a hotel

ON the corner of Rizal Avenue and Doroteo Jose stands the Manila Grand Opera Hotel, a fabulist if the establishment were a person.This is about the history of a place that has gone through many costume changes, a story bursting with intersectionality, with a past so implausible it should be celebrated annually by poets and climate activists alike.

A post of remembrance from Alpha Phi Beta

The Constantino Foundation appreciates the post of the Alpha Phi Beta Fraternity of UP, which Renato Constantino was very much part of along with stalwarts such as Abraham Sarmiento and Hermon Lagman. In their post, the fraternity quotes our founder as a reminder to today's youth: "????????????????????, ???????? ???????????????? ???????????? ???????????????????????? ???????????? ???????????? ???????????????? ???????? ???????????????????? ???????????? ???????????????????????????????? ????????????????????????????????...

“A Past Revisited was both a revelation and a challenge. It made us see the familiar narratives of Philippine history in new and unsettling ways. It invited us to ask deeper questions—about power, about colonial legacies, about the struggles and aspirations of our people. And it also gave us a sense of responsibility: to carry history forward not just as memory, but as a guide for action and transformation.”

Dr. Chas M. Navarro
Commissioner, National Historical Commission of the Philippines (NHCP)

“Thank you very much, Constantino Foundation! It was a lovely afternoon spent learning about history, poetry, art, climate change, street names, the bicycles in revolution, kickass heroines, and much more! Renato Redentor Constantino’s talk and Renato Senior’s book A Past Revisited really got under my skin. Maraming salamat!”

“Street names and the persistence of memory,” June 2024
“Frequented the area in the early ’80s because of Popular Bookstore (small door, beside the gate of Mapua High School), the only one that carried engineering books required for our course. It was still Martial Law… One buys … dangerous reading materials afraid of the Secret Marshals who were then infamous for salvaging (tokhang in the time of tatay digong) petty criminals and activists. Across Mapua High then was a parking lot of mini buses – now the Manila Grand Opera.”

“We have been so wonderfully blessed in the past week by the presence of tremendously inspiring people, one of them, the one who likes to “shake trees”, is Sir Renato Redentor Constantino who moved the entire plenary to feel, think, and act… people couldn’t help but share and talk about the presentation. I told Sir Red that by the second day of the event, people realized there were ‘deeper commitments than professionalism.’”

Floraime Pantaleta
Executive Director, Ateneo Zamboanga-Mindanao Institute
“Renato and Letty kept the fire burning for country and people, fueled by their abiding love for each other and the cause they both pursued with single-minded devotion. In this sense, Renato and Letty may well be considered among the principal characters in one long epic love poem about the birthing of a free and caring society, still unfinished to this day.”

Dr. Rosalinda Pineda-Ofreneo
biographer, at the Pasts Revisited exhibit opening, Yuchengco Museum,
11 June 2026
“My first brush with Renato Constantino was through Mr. Herman Rochester, our 4th year high school adviser, who lent me his Miseducation of the Filipino. From then on I was hooked. In college, I encountered Parents and Activists, which helped me understand my parents’ objections to my activism, then his books A Past Revisited and A Continuing Past which made me learn history in a way that I was never taught in my elementary and high school years. His and his wife Letizia’s many articles, pamphlets, books and publications were guiding lights that stirred up the makabayan and palaban in me. Theirs was a writing that was nakakapagmulat at nakakataas ng pag-unawa.”
