Mendieta's chapter on the trades writes that the stonecutters \"eran curiosos en la escultura (como queda dicho), y labraban sin hierro con solas piedras cosas muy de ver\", and that \"despues que tuvieron picos y escodas y los demas instrumentos de hierro, y vieron obras que los nuestros hacian, se aventajaron en gran manera, y así hacen y labran arcos redondos, escacianos y terciados, portadas y ventanas de mucha obra\". The praise is for work already being done without iron; what arrives is the pick, the escoda and a repertoire of arches.",

Francisco de México, por mano de un cantero de Castilla), maravilláronse mucho los indios en ver cosa de bóveda, y no podian creer sino que al quitar de los andamios y cimbria, todo habia de venir abajo\", so that none of them would walk beneath it while the centring came down; \"mas visto que quedaba firme la bóveda, luego perdieron el miedo\".

What Torquemada adds is his own, and it is first-hand: of the church of Santiago he writes that the Indians \"la han trabajado... sin mas industria, ni Maestro, que Yo, que he sido el que la he traçado, y ellos puéstolo en execucion con sus manos, así en la Mampostería, como en la Cantería\", and that \"ellos han hecho las Cimbrias, y las han desbaratado\" — the centring built and struck by the same hands that laid the stone.",

Y ellos la hacen tan perfecta, que no se puede mejorar.\" Torquemada repeats it in his own spelling and adds, of the stonework of Mexico City, that \"por sus manos pasan las Obras, que los Españoles hacen, que por maravilla ai alguno de ellos, que ponga mano en esto, por mas Oficial que sea\".",

The retablo of the high altar, set in place in 1609 and appraised at twenty-one thousand pesos, was likewise laboured \"de valde\", its painting by \"un Español Vizcaìno, llamado Baltasar de Echave, unico en su Arte\". The same page notes that the Franciscans, who had refused the royal stipend while the Indians' alms sufficed, now took it \"por no ser cargosos à los Indios, que en este tiempo estàn pobres\". A ninety-thousand-peso building, unpaid labour, and an order recording that the people who paid for it had become poor: all three are on one page, in the words of the man who traced the plan.",

Both authors are Franciscans writing the history of their own order's mission, and on the Tlatelolco church Torquemada is also the architect assessing his own work; the two texts are textually dependent for the vault story, so the episode has effectively one source behind it. Neither page gives a date for the first vault, the name of the Castilian mason, the terms on which labour was summoned, wages where any were paid, or the legal instrument behind the drafts; Torquemada's \"de valde\" is offered as devotion and this object does not read it as anything more than what the word says. No archaeological or architectural study of the Tlaxcala chapels or of Santiago Tlatelolco was opened here, so nothing is claimed about what survives on the ground today.",

Almost none of it quotes the two chapters where the chroniclers say who cut the stone and who struck the centring. This object opens both — Mendieta's libro IV capítulo XIII and Torquemada's libro XVII — and prints the vault passage entire, including the detail nobody repeats, that indigenous masons built two vaulted chapels unaided at Tlaxcala soon after the first vault went up in Mexico City. It then does the thing a triumphal account will not do: it says the two chronicles are textually dependent and therefore one witness, and it turns three pages on in Torquemada to the passage where the architect of Santiago Tlatelolco records that his ninety-thousand-peso church was built by masons, bricklayers and labourers working \"de valde\", at a time when, by his own account, the Indians had become poor.",
