of law to new needs was given over to juridical practice, to magistrates, and especially to the praetors. A praetor was not a legislator and did not technically create new law when he issued his edicts (magistratuum edicta). In fact, the results of his rulings enjoyed legal protection (actionem dare) and were in effect often the source of new legal rules. A praetor's successor was not bound by the edicts of his predecessor; however, he did take rules from edicts of his predecessor that had proved to be useful. In this way a constant content was created that proceeded from edict to edict (edictum traslatitium). Thus, over the course of time, parallel to the civil law and supplementing and correcting it, a new body of praetoric law emerged. In fact, praetoric law was so defined by the famous Roman jurist Papinian (142–212 AD): "Ius praetorium est quod praetores introduxerunt adiuvandi vel supplendi vel corrigendi iuris civilis gratia propter utilitatem publicam" ("praetoric law is that law introduced by praetors to supplement or correct civil law for public benefit"). Ultimately, civil law and praetoric law were fused in the Corpus Juris Civilis. Classical Roman law The first 250 years of the current era are the period during which Roman law and Roman legal science reached its greatest degree of sophistication. The law of this period is often referred to as the "classical period of Roman law". The literary and practical achievements of the jurists of this period gave Roman law its unique shape. The jurists worked in different functions: They gave legal opinions at the request of private parties. They advised the magistrates who were entrusted with the administration of justice, most importantly the praetors. They helped the praetors draft their edicts, in which they publicly announced at the beginning of their tenure, how they would handle their duties, and the formularies, according to which specific proceedings were conducted. Some jurists also held high judicial and administrative offices themselves. The jurists also produced all kinds of legal punishments. Around AD 130 the jurist Salvius Iulianus drafted a standard form of the praetor's edict, which was used by all praetors from that time onwards. This edict contained detailed descriptions of all cases, in which the praetor would allow a legal action and in which he would grant a defense. The standard edict thus functioned like a comprehensive law code, even though it did
