self-portrait at 20, three years before she became the second woman to join the Haarlem Guild in 1633 Guild rules varied greatly. In common with the Guilds for other trades, there would be an initial
apprenticeship of at least three, more often five years. Typically, the apprentice would then qualify as a "
journeyman", free to work for any Guild member. Some artists began to sign and date paintings a year or two before they reached the next stage, which often involved a payment to the Guild, and was to become a "
free Master". After this the artist could sell his own works, set up his own workshop with apprentices of his own, and also sell the work of other artists.
Anthony van Dyck achieved this at eighteen, but in the twenties would be more typical. In some places the maximum number of apprentices was specified (as for example two), especially in the earlier periods, and alternatively a minimum of one might be specified. In
Nuremberg painting, unlike say goldsmithing, was a "free trade" without a Guild and regulated directly by the city council; this was intended to encourage growth in a city where much art was becoming linked with book
publishing, for which Nuremberg was the largest German centre. Nonetheless, there were rules and for example only married men could operate a workshop. In most cities the women who were important members of workshops making
illuminated manuscripts were excluded from the Guild or from being masters; however not in Antwerp, where
Caterina van Hemessen and others were members. As the Christian title of the Guild suggested, Jews were excluded, at least from becoming masters, in most cities. When
printmaking arrived, many
engravers were from a
goldsmithing background and stayed in that guild. As that link weakened with the development of printmaking, some painters' guilds accepted engravers or
etchers who did not paint as Members, and others did not. In London painters on glass had their own separate guild with the glaziers; elsewhere they would be accepted by the painters. The rules of the Delft guild have been much puzzled over by art historians seeking to illuminate the undocumented training of
Vermeer. When he joined the Guild there in 1653, he must have received six years training, according to the local rules. In addition, he had to pay a six guilders admission fee, despite the fact that his father was a Guild member (as an art dealer), which would normally have meant only a three guilder fee. This appears to mean that his training had not been received in Delft itself.
Pieter de Hooch on the other hand, as an immigrant to Delft, had to pay twelve guilders in 1655, which he could not afford to pay all at once. Another aspect of the Guild rules is illustrated by the dispute between
Frans Hals and
Judith Leyster in Haarlem. Leyster was the second woman in Haarlem to join the Guild, and probably trained with Hals – she was a witness at the
baptism of his daughter. Some years later, in 1635, she brought a dispute to the Guild complaining that one of her three apprentices had left her workshop after only a few days, and had been accepted into Hals' shop, in breach of Guild rules. The Guild had the power to fine members, and after discovering that the apprentice had not been registered with them, fined both artists, and made a ruling on the apprentice's position. ==Decline of the guilds==
