The paper considers the use of infinitives and subjunctive forms as modal patterns of indirect speech attested in Russian Chronicles of the XI–XVI centuries. In early texts, an infinitive in a subordinate clause describes either a speech act that must be put into practice or a situation destined to happen. Subjunctive forms are used only in citations containing requests. The illocutionary power of reported speech is regularly marked with an illocutionary verb. In later chronicles, infinitive clauses and subjunctive forms begin to alternate in modal patterns of indirect speech containing official orders. However, the modal patterns are not yet attested as a substitute of imperative mood in subordinate clauses.
