This same year, Antonio Neri's father, Neri Neri, was commissioned along with three colleagues from the physician's guild to make a complete revision of the Ricettario Fiorentino.  This was the physician and apothecary's reference used throughout Europe and in Tuscany it carried the weight of law; every medical professional was required to own a copy and adhere to its prescriptions. The first edition had been published almost a century earlier; it was revised periodically to keep it current with the latest thinking and remedies.
Reviewing the book's recipes is of course interesting. The final prescription is one for chicken soup, the preparation of which would certainly make most modern patients turn a bit green. An attempt to look beyond the technical methods is also intriguing; we are rewarded with a glimpse into the personalities of the men who wrote the book. One of the authors in particular has a story that illustrates how shrewd maneuvering can be used for good, even in times when self-serving and corruption were endemic.
The four authors' names do not appear in the book itself, but they are documented in a letter from the college of physicians acknowledging the directive of the grand duke and pledging to purge the text of any preparations that could be dangerous.  In addition to Neri Neri and Francesco Rosselli (son of the royal apothecary), the other two co-authors were Giovanni Galletti and Giovan Battista Benadù.  Giovanni Galletti, is difficult to pin down. His family resided in Florence and he exchanged letters with a Filippo Galletti in Rome, who may have been a brother or cousin. Adding intrigue to the connection, Filippo was working as a confidential correspondent—read: a spy—for Ferdinando I de' Medici around 1600.  The fourth co-author, Benadù, a physician and surgeon from Fivizzano, north of Pisa, died in 1603.  His will provided for an annual gift to Santa Maria Nuova hospital  and another to the Ospedale degli Innocenti, a gift that amazingly supported the orphanage into the nineteenth century. 
Little information exists about these men, it would seem impossible to extract any meaningful insight into their personalities, but perhaps we can take a small step in that direction. Neri Neri's coauthor, Benadù, administered his financial gift to the Ospedale degli Innocenti with a large dose of shrewdness. The measures he took to ensure the purposeful use of his money, even after his death, reveal a man who cared a great deal about the less fortunate. In the 1400s, the wealthy silk merchants’ guild started Innocenti to be responsible for the welfare of abandoned children. By the late 1500s, the orphanage struggled under a mountain of debt. Grand Duke Ferdinando made a concerted effort to improve the situation and it became a well run, efficient institution, although throughout its history, it was not without problems. Over centuries of operation, it had seen the abuse of children and exploitation by both parents and the government. Famine hit Tuscany on a regular basis and less of it was due to natural causes than one might imagine. The grand dukes tended to make large trade deals, with Spain and other states, which depleted supplies and drove the local price of grain beyond what poorer families could afford. In those hard times, the Ospedale degli Innocenti experienced overflows of abandoned children. It was discovered under Cosimo I de' Medici's rule that some desperate families had found creative ways to take advantage. Destitute mothers left their infants at Innocenti, where children were assured of a square meal, a warm bed and an education. The same mothers then sold their milk to the orphanage, in effect collecting a wage to wet nurse their own children.
Florentine accountants invented double entry bookkeeping, and the Medici gave that innovation a good workout. They pioneered the use of municipal bonds, the purchase of which was sometimes made compulsory. At the time, they were a novel approach to fund a city’s development, and selling bonds under the banner of the orphanage was an early bit of marketing genius. It is unfortunate that the money often did not stay with the orphanage, but the obligation to pay off these debts did. The Medici often raided the accounts to pay for other projects both civic and personal. Under Ferdinando, the situation improved, but was far from stable. Through a clever maneuver, Benadù ensured his money went to the orphanage alone and not to bondholders. He left an inheritance for the day-to-day operation of Innocenti, putting control in the hands of the monks at the Badia Fiorentina monastery, where it was beyond the reach of greedy hands.
The 1597 edition of Ricettario Fiorentino produced by Neri Neri, Francesco Rosselli and their colleagues proved so popular that Grand Duke Francesco II  ordered it reprinted without changes in 1623.
