Lukačić's exact date of birth is unknown; in 1587 he was baptised in Šibenik where it is believed he was born. Ten years later he entered the Franciscan order when he accepted his monastic name Ivan. In 1600 he was sent to Italy where he studied theology and music. In 1612 he has signed himself as baccalaureus, while on 23 March 1615 he was awarded in Rome the degree of Magister Musices . In 1614 he participated as maestro di cappella at the feast of St Jerome in the Saint Jerome of the Slavschurch in Rome. He returned to Šibenik in 1618 and two years later he moved to Split, where he became prior of the Franciscan monastery in addition to being director of music at the Cathedral, where he lived until his death. While Lukačić's sojourn in Italy is insufficiently documented, his engagement in Split, both as a prior and musician, left quite a record of first-class importance for the musical life of that time in Dalmatia.

According to the title page and dedication, Giacomo Finetti, at that time maestro di cappella at the church dei Frari in Venice, handed them to the Archbishop of Split. A total of 27 motets were probably written during Lukačić’s long stay in Italy. Characteristic of his monodies are clear melodic lines and the simplicity of harmonic flow. Monodic motets such as Cantabo Domino, Sicut cedrus, and Oscluletur me, which like the majority of the pieces from the collection resort to biblical texts or liturgical readings, are brilliantly balanced miniatures. Among two-part motets, Da pacem, Domine is of exceptional virtuosity, while the three-part Domine, puer meus contains an oratorio-like dramatic dialogue between Christ, the narrator, and the centurion. The four-part Quam pulchra es has choralprima pratica sections, Gabrielian refrains in a dance-like rhythm, while solo parts are in the new seconda pratica style. At the beginning of the 17th century the new baroque style was already accepted in Dalmatia, and Split, where composers like T. Cecchini and M. Romano were active, was one of the most important musical center. Lukačić achieved a fine synthesis of the early baroque Venetian church style and local traits.
